Code 32: A check battery clean and tighten + plus- battery cables . Recharge and replace battery. B: replace engine oil with oil of proper viscosity for the ambient temperature.note hight viscosity can slow down cranking speed. There you go
@wagh , what I'm doing wrong?? I run them about 60-70hrs a week for real work, not a rv or powering a TV but to run full mobile medical repair truck, been doing this 15 years they simply won't hold up to real commercial use, the air cooled models only have a life of 5000hrs and at almost 300hrs of run time a month they require a ton of maintenance due to parts failing
A company I worked for, had an Onan diesel generator in one of their vehicles. It had a random stall issue. I took it to an RV repair shop that was Onan certified. They replaced the circuit board and it died again on a job. Took it back and they replaced the crank sensor. Died again on a job. This time I did my own troubleshooting and found it didn't have fuel pressure. I replaced the fuel pump and it didn't stall after that.
Not true, I have an Onan 5k generator that is 30 years old, It's reliable, and starts right up with 1 or 2 pulls of the starter rope. Of course, maintenance is the key.
@wagh mine is only 18 months old, stalls out 3 to 5 times before it eventually stays running, and at around 40 hours developed a fuel line leak which sprayed diesel everywhere and took 10 days to repair under warranty. They never figured out the hard start/stalling issue. What maintenance am I overlooking here? It’s already had 2 oil changes. Is there some voodoo ritual or human sacrifice I should perform, to make this POS run right?
@@w3vjp568 try checking your fuel flow, particularly the filter. Mine had a shitty filter from factory and I replaced it and it never had another issue.
Sweet a rolling house that gets used once a year and breaks down all the time, so you get to spend a endless amount of money in repair costs, can’t wait to get one and park it in front of my neighbors house.
Actually, there is a scan tool for the Onan generators. It's pc based to be used on laptops and called Onan InPower Lite. It's generally a dealers tool and requires a number of adapters for the various models of gas, propane, diesel, hybrid, and inverter power systems they offer. This is usable on all units that have the A1 control system. Through the software it will tell you the conditions of the code along with any other codes that have been registered in the A1 controller. On some models you can monitor parameters for diagnostic purposes, adjust from American to European power specification standards and log data for diagnostic collaboration with the top techs at Cummins Onan for warranty repairs beyond the basic and simple. The run indicator light will give you the last logged code three times in a row. Then if there is another code it will run that code for three cycles and so on for three minutes. If there are no other active codes it will repeat the initial code that was given. The most common issues that I've came across running repair for rental fleets and over the phone technical assistance for 20 years was the batteries being low from a night of dry camping and a low fuel level from getting below the RV manufacturers anti-strand generator pickup that can be in the 3/8 to 1/4 tank level. When manufacturers put in the generator pickup tube it's not an exact placement. Beyond that the diesel generators have an ambient air temperature sensor that will activate a dwell timer setting in the A1 controller for colder temperature starting parameters but there are a lot of things going on when you hit that start switch. Also if you have the code stop and you want to restart the code flashing there's a simple process to that too. First, hold the start/stop switch in the Stop/Prime position until the light comes on to wake up the A1 Controller and release the switch once the light comes on. Next, press and release the Start/Stop switch stop position three times. At this point the light will begin flashing again allowing you to retrieve the code(s) for lookup. For the most part the most common code that you will ever see is the code 36 which is basically the A1 Controller saying the generator is stopped without being told to stop. This is the code that all Onan generators rest on when there are no issues triggered by a failed parameter and also when you run out of fuel. I'd elaborate from there but that would take all of the fun out of the RV experience for everyone. Happy camping from a 20 year Onan Level 3 Gas/Diesel/Hybrid/Inverter Tech.
Super easy fix for Onan generators. As soon as you notice your RV has been infected with this generator remove it immediately by any means and buy a Honda like a real person. You just saved thousands of dollars. Youre welcome !
The Onan generator flash code 32 typically indicates an issue with the low coolant level or a faulty coolant temperature sensor. It suggests that there might be insufficient coolant in the system or a malfunctioning sensor that is not accurately detecting the coolant temperature. It is important to address this issue promptly to prevent potential damage to the generator and ensure proper functioning. Consulting the generator's manual or contacting an authorized service technician would be advisable to diagnose and resolve the problem correctly.
Load banking your generators annually will prevent a lot of problems in the future or address things that needs attention. So your generator will work when you really need it.
Make sure you have a min of a 1/4 tank of it pulls of the RV tank for starters...just like making sure the run switch is on. Seems simple but when i was a tech for Onan it was 1 in 3 service calls that it was one of those 2 simply over looked, usually the "less than 1/4 tank" being the most common.
The fault code 32 means that the crankshaft of the engine is turning at a speed below 180 RPM for two seconds, which can be caused by several problems,
My father in law had this problem in a fith wheel trailer. It was a low level of dirty oil problem. He changed the oil and it worked. Not saying that's your problem, but usually it is something simple on these like the condition of the oil, a clogged air filter, a worn spark plug, or a loose/dirty battery connection.
How can you tell the difference between a real onan carburetor from the ones on of Amazon for $20-$50? I bought anew onan off of ebay close to $500 and I'm having problems. Maybe he bought the $50 one and put it in the Onan box's and sold it as original one .thank you for all your great videos. I hope you can answer this question from me.
Where are you this time? Looks like out in the Jct! How many different shops do you work at, seems like different places every video. Thought you were down the road from me, place with all the palm trees across the street.
Good info on how to read trouble codes on an Onan. We have 03 Newmar with a Generac 7500. Any idea how to pull up codes on that? We're haven't had any issues, yet, but like to be prepared. Thanks
Hey I have a semi with Electric APU and my inverter shuts down after running only an hour. My batteries are good. I replaced factory Inverter with new one and I think its' because the new one shuts down to save batteries when I need it to work till batteries are dead I think. it is a pure sign inverter. know where I can get help?
We’ve had some problems with our onan. It will die if we use the microwave. Didn’t do that when it was new. Just installed a smaller wattage microwave, it seems to be doing alright now. If we have things like the tv on, along with air conditioning it will sometimes die randomly.
Sounds like it's dying when you apply a load to it, so this usually means that the engine is not making enough power to keep itself from stalling under load. It could be the air filter, a worn out engine, maybe a faulty aneroid valve, fuel filter, worn out fuel pump, etc.
Were you in Season 5 Episode 9, of Star Trek; The Next Generation? In this episode, the crew's attempts to save the inhabitants of Penthara IV from the devastating aftereffects of a massive asteroid strike are interrupted by the arrival of Berlinghoff Rasmussen, a purported historian from the 26th century, who claims to be studying their era.
code 32 is leading to few things 1st bad battery check voltage meter if above 12v or 13v good under 11v or 10v bad battery or need charge up check date of battery if older than 4 years need be replaced 2nd bad battery cable connection clean connection make sure no green stuff (it eat away connection which rotten away) 3rd starter is worn out not able turn fast enough before you replaced starter besure check make sure nothing is dragging on it by turning crankshaft with hand if turn fine then bad starter if no or hard turn them there generator bearing is shot (worn out or frozed up) 4th if all this is replaced still not turning fast enough tham replaced both cable from generator to battery (because some of copper inside of rubber cover can broken unseen) 5th still same thing take air filter off and shoot some starting fluids in it see if start if it does them likely bad crankshaft sensors and not getting any fluid into carburetors to start engine im engineers i normally do ton of work on anything just save yourself a headache for tips try before take it to shop if you have zero skills them shop is only choice
My RV technician husband told me to say “code means…. Check everything because everything is possibly broken”. Batteries dead. He says code 32 Is spark plugs etc
He's laughing because there's a page of steps. This is why I love when customers have scanners and check their engine codes then tell me they need a specific part replaced. I usually advise them to just pay the diagnosis fee and let me find the actual fault. Some say no and I replace the part then it doesn't fix their problem so they get mad and I tell them, you own a scan tool but you don't know how to diagnose.... Now that we got that out of the way, I'll diagnose and find the fault and fix it so you can be on your way
Code 32: Your warranty has expired
😂
🤣🤣🤣
We've been trying to get ahold of you to tell you your warranty is about to expire.
Yep, and installed in an RV. Therefore, you must buy a new RV.
Made me laugh out loud
Code 32: It ain’t got no gas innit
I like fried taters mmm hmm
😂😂
With mustard
well, it is a good thing i have a friend with a spare can of diesel sitting around
🤘🤣🤘
Code 32: A check battery clean and tighten + plus- battery cables . Recharge and replace battery.
B: replace engine oil with oil of proper viscosity for the ambient temperature.note hight viscosity can slow down cranking speed. There you go
👌 cool
That’s what I tough cuz my car makes the same noise when the battery is empty
I pulled my 4 KW Onan and installed a 4 KW HONDA.
Never ran better.
Ya Honda rules although Yamaha is a better value IMO
Yep
Or quieter
Code 32: "buy a Honda generator "
I run Onan 5 days a week, valve dropping, head cracking junk, eat a set of brushes every 8 months too
Gotta love military grade
Brushes are cheap, any other methods to regulate voltage cost the price of the generator if they fail. 8 months of consistent run time is 👍👌
@alexmills1329 military grade is "cheap and works just good enough "
and that's why you don't get rid of your pre-Cummins Onan.

I always wondered how they ran the AC and electricity when the engine was off, thank you for showing me.

Certified in throwing the parts cannon at problems and costing customers money 😂
I first read it didn't start after that 😂😂😂
Nothing generates smoke, noise, vibration, and trouble, better than an Onan.
At least it's heavy
I've had much better luck

Same as a boat
So does that include all the Harley owners that live in the North asking for a friend?

You know what it is to be on the road and no electricity for the ac . Thank man !!!!
Super easy fix for Onan generators. As soon as you notice your RV has been infected with this generator remove it immediately by any means and buy a Honda like a real person. You just saved thousands of dollars. Youre welcome !
I am confident you have not priced out the replacement of this generator
Low crankshaft rotation. 180rpm for 2 minutes or more. Many possible causes. Good Luck! 😂
or oil is low
Battery is dead.
Flux capacitor isn't fluxing
@@danielfinney4295 oh flux!
Now everything has a computer in it! I recently found my older washing machine had trouble codes. I studied it, fixed it myself.
Back in the 80's that's how I accessed my ECM codes on my Camaro ...Well I used a paper clip..lol

The codes are in the manuals.
Load banking your generators annually will prevent a lot of problems in the future or address things that needs attention. So your generator will work when you really need it.
Code 32: Time to go buy a Generac generator.
It only has 42 days of use. 1002.3 hours.
Onan was bought out by Cummins.
heck no winco! champion! honda... no generac.
Make sure you have a min of a 1/4 tank of it pulls of the RV tank for starters...just like making sure the run switch is on. Seems simple but when i was a tech for Onan it was 1 in 3 service calls that it was one of those 2 simply over looked, usually the "less than 1/4 tank" being the most common.
Code 32...crank spins on start up below 180 rev per minute... ***likely cause is a poor ground or power conection***
There are 2 or 3 fuses inside that panel. Usually its one of those.
Omg! Thank you! I am having that exact issue!!
So it's basically obd1 in 90s cars that just flashed the code on the dash
I remember using a paperclip to jump a couple pins on old GM's. Was kinda fun tbh.
@@joecrisp9060 that's what I use to do on my 88 1500 and 90 lumina
Nice ...now I need to go buy a large moving house...
Onan code 32... low oil OR low cold cranking voltage on the battery.
Where did you get low oil, code is crank is turning at less than a 180 rpm.
Biggest pain in the.....
Onans are amazing, but i swear the engineers were drunk when designing reliability on these units !!
Thanks for the video.
Change the oil. Viscosity will certainly cause this issue, next battery
The wonderful Onan generic codes.
The fault code 32 means that the crankshaft of the engine is turning at a speed below 180 RPM for two seconds, which can be caused by several problems,
Thank you for your advice.

Similar to Volvo in the 80s and 90s where on the computer port it could flash a light at you and give you a code

People like this is why the world revolves day after day
Wow, you’re so smart it’s not like it’s literally written right next to the switch that you cover with your hand
It's not explained there. I am smart
I'll give you the shortcut take the own out and replace it with any other brand
I've never seen anything but an Onan generator on an RV.
sounds like analog diagnostic system. like pre-OBD 2 systems for car before 1996
I know they won't run past 1/4 tank if I remember correctly
Correct, thats so you don't wake up to an empty tank in your rig.
Sure, except no blinking lights on my Propane 6KW Onan from 1991.
Good info on how to read trouble codes on an Onan. We have 03 Newmar with a Generac 7500. Any idea how to pull up codes on that? We're haven't had any issues, yet, but like to be prepared. Thanks
Check your battery connections, check your oil level...
I use to keep a little Honda pullstart just incase 😊
Hey I have a semi with Electric APU and my inverter shuts down after running only an hour. My batteries are good.

Nice RV
Code 32 mean that the crankshaft is cranky and misses his misses in the service house. Get it serviced.
Code 32 means DEEEEZZZZZZ NUTTSSSS !! Haha, got em 🤣🤣
the obd 1 system was very good ,, no need to make it more complicated
Code 32: we been trying to reach you about your car's extended warranty
Thank you very much
Awesome never knew that trick.
Slow cranking code. Check power and grounds. Most likely just a dead battery
That is so cool 😎
ours was the house batterys (all 6) did not hold enough charge to start it. getting to those batterys and getting them changed was kind of a bear.
We’ve had some problems with our onan. It will die if we use the microwave. Didn’t do that when it was new. Just installed a smaller wattage microwave, it seems to be doing alright now. If we have things like the tv on, along with air conditioning it will sometimes die randomly.

Its always preferable to do this especially when you need help. Cause people are crooked.
What was the code for!! OMG I need you to tell me. Don’t make me google it.
low cranking engine speed
Code 32, replace with a better generator.
Excellent tips
OBD for Onan...nice
Low voltage or incorrect oil viscosity. The crank isn’t turning or is slow
Were you in Season 5 Episode 9, of Star Trek; The Next Generation?
In this episode, the crew's attempts to save the inhabitants of Penthara IV from the devastating aftereffects of a massive asteroid strike are interrupted by the arrival of Berlinghoff Rasmussen, a purported historian from the 26th century, who claims to be studying their era.
Oh neat thats like with obd1 cars
OBD0 No?
The younger generating will have trouble if they ever have to work on OBD1.
code 32 is leading to few things
1st bad battery check voltage meter if above 12v or 13v good under 11v or 10v bad battery or need charge up check date of battery if older than 4 years need be replaced
2nd bad battery cable connection clean connection make sure no green stuff (it eat away connection which rotten away)
3rd starter is worn out not able turn fast enough before you replaced starter besure check make sure nothing is dragging on it by turning crankshaft with hand if turn fine then bad starter if no or hard turn them there generator bearing is shot (worn out or frozed up)
4th if all this is replaced still not turning fast enough tham replaced both cable from generator to battery (because some of copper inside of rubber cover can broken unseen)
5th still same thing take air filter off and shoot some starting fluids in it see if start if it does them likely bad crankshaft sensors and not getting any fluid into carburetors to start engine
im engineers i normally do ton of work on anything just save yourself a headache for tips try before take it to shop if you have zero skills them shop is only choice
There is a scan tool. It's called inpower
code 32 I think is
loose/dirty battery connections, the oil is not the right viscosity or batteries need to be replaced.
Are you in the hi desert of California per chance?
Its a code for replace your generator with another brand ...
There is a schematic on the unit.🤭
Hun, why is Billy Bob Thornton working on our RV?
RV tech , Onan certified. They used to be the sh.t. new stuff not so much.
Onan was the hardest to get parts. It was always match things up
The error code is 32 which states that it is either low on oil or the battery doesn't have enough cranking power to start it for more than 2 seconds.
Is it just me or does he remind anybody else of Billy Bob Thornton
Coolant temp sensor I think?
To spare those the effort of googling, 32 is dirty or loose battery connections or oil viscosity not right..
Probably low oil. Some have sensors so it won't run on low oil... just my thoughts
If you have a generator that is not starting, it is an Onan.
Used to work for Cummins parts sales, the engineering is great but the company treats it's employees like trash
Cool beans 😎
Just like the early 90s GM check engine light
Who else googled this code even though don't have a rv or 1 of these generators? Battery dying.
Code 32: Even Odin can't help you.
Gen tech here... the problem is, it's an Onan.
Mine isn’t even showing a light or sound. Like it’s totally dead, any suggestions?
Code 32 low crankshaft RPM could be caused by a lot of stuff
Low? Not turning over at all
so no answers here got it thanks for sending me to the next vid
My RV technician husband told me to say “code means…. Check everything because everything is possibly broken”. Batteries dead. He says code 32 Is spark plugs etc
What happened to owners manuals ??
