I looked everywhere for a quick and easy diode install. All I found was 10 minute videos explaining every bit of knowledge about diodes that I didn’t care to listen to. Then this video came up! 🙏🏽 thank you my brother!
Hey Jerry! Question! Could you theoretically use a rheostat in place of the resistors? That way you could turn up to 16v when slamming and back to 13.6 ish when cruising? I'm a mechanic so thought what you were doing with adding in different resistors was really smart. I could see a voltage knob in the car and crank it up at will. 😁
Hey Jerry I really appreciate all the videos if you do enjoyed my demo I got from the sundown audio show I do have a question can you run diodes on AGM I HAVE THREE XSPOWER D3400 WITH 220AMP ALT but my car will not let it charge past 13.8
HY jerry my car also has the smart charge alt. Does the Ford Edge hav a 3 wire alt plug or a single wire plug? My car has a single wire plug an would like to know if the diode trick would work in my case
So because the diodes go on the “Sense” wire, the natural voltage drop across the diode makes the Voltage Controller in the Alternator think it’s putting out less voltage so it raises the output voltage by the amount the diodes drop it to compensate.
GOT one smart altornator, who dropp in charging when im just let the car run in neutreal and play Music!! Some advice, can i do something or is diode the thing, whats the resistance if i whant to jump to 14.5-14.8
Jerry i got a kit from mike singer to bump up my voltage from 13.8 to 15.5vs for i can run my scib 100ah bank. Do you know how many i would have to run to get there? Ive never done this before and kinda worried to do it
So i have a 400 amp alternator from mechman alternator in a 1994 g20 van 14.8 is where it's resting at charging, adding a 1 diode, should put it at 15.8, and im on full lithium do i have to undo the battery before installing the diode?
@Rowboyto just now seeing this. It was a 12 camry. I ended up replacing my underhood "alt-s" fuse with diode fuse and it did the same thing. I now have a 21 camry which uses LIN so now I have a different setup.
Will this work on a 2017 Chrysler 300 I’m suing a mechman alternator and I think my alternator has a 2 wire system will this work or throw my computer off
Jerry is this the only diode video you have or you have one showing the alt up closer etc? I'm charging at 14.2 and need to bump my power bastards HO alt up to 14.8 for two xs power 14v lto batteries. I've never done this diode trick before and am stoked to see their is one. I just don't want to F anything up lol.
@jerryaintloud so could I do this on a 320 amp alt for a 2002 ford expedition even tho it’s internally regulated ? It’s from Tucson Phoenix alternators out of Arizona I charge 14.8 now but want to be at 15.5 any way I could pay you to make me one of these harnesses if possible ?
What I just did for hooking up cmax is hook 2 0gauge power runs and the front battery cable to positive post on alt using illz customz adapters on alt to positive on cmax fuse under hood and at battery 200amp on each 0 gauge run totaling 400amp since alt does 370amp. Then run two 0 gauge grounds from cmax ground to alternator case mounting bolt with front battery negative cable. Also run ground cable from cmax to frame. My front battery is still under hood for looks and boosting if I drain cmax. I may put supercap if it takes 15.8v
Do you know of any other diodes to use other than 1N4004 because 2 diodes is putting my charging as high as 16.4 at times. Usually 16.0 but sometimes I'll see 16.4 and my radio doesn't like it and neither do my gauges in my truck.
Couldnt you make links like you just did for individual diodes that plug and play like yours just did but solider the diods to the connector. This would also mean if one died you could easily remove it and continue.
I would just put a distro block under the hood and run all lithium. I ran on an isolator for a year and had nothing but issues. When I finally took my AGM out the system was so much more solid.
it doesn’t work like that, you would need to change battery config, for instance, building a panasonic cmax/insight bank in a 12s3p config would give you a 15ah 44.4v lithium bank that should work for your ebike. but it would be a big and bulky bank as you would need a bms for balancing, overcharging and undercharging protection and most importantly, compression for the cells as charging can cause them to swell.
Few questions Jerry, if you don’t mind. Whats the sense wire? Is that the one that goes to the battery? How does this affect the charging of the battery. Does it f up the battery or the ecm or them dang computer modules? Thanks in advance brother.
the sense wire is the battery voltage and tells the alt what to charge at, the diode in that wire makes it read 1/2 volt lower so the alt puts out 1/2 volt more ect.
@@JerryAintloud So then were tricking the alts regulator into thinking the battery is lower in voltage that what it actually is forcing it to up its voltage. I've never seen this before and was trying to figure it out. Coz I'm thinking the diode is for make power move in one direction. It wasnt making sense. Lol
@REG3305 it's telling the alternator that the battery is low and needs to charge. The more diodes you add. The more the alternator charges bc your battery tells the alt that its lower than what it actually is.
@@bhojho93 can't really remember but just get a couple and see what works best for you. Some are very sensitive as they will send your alternator to see as high as 20 volts. Mine starts at the bottom with the knob turned all the way down at 15.5 and goes up to 18. So just kinda of play around with what you might need. I can actually find one that would go smaller than that but I'll wait til it goes out. Surely someone knows what size you might need. I just got an assortment of them and went with it. They work alot better than the diodes.
What about PCM controlled? Would this work? I have a 2012 Kia sorento and I have to have an accessory on to get the 14.6. Anything else it’s 12.9 and I need that 14.8 for my lithium bank. If not I’ll have to spend another $300 for a external voltage controller

Glad it helped
Can I run them with 2 Northstar batteries and stock alt
That's pretty slick and well demonstrated foreal. By chance should I add a fuse or relay ? Thanks for the vid because this could help alot of folks

Do a Diodes and potensiometer together
@@stavros419 no.
6k ohm unit will get you exactly the results your after..
Should use the red spade connectors and put done hear shrink on that. Then it'll also be a little more weather resistant.

Thanks chief. I was wondering what the direction the stripe faces. (For those wondering its towards the alternator). Thanks boss!
Is the alternator still running good with 16v?
Can you add a potentiometer on that to adjust voltage
Would it work just to attach the diodes to the alternator fuse instead of cutting the wire? Just attaching one big diode?
How do you find the sensor wire?
What wire do you have diodes connected to? Is that the wire that goes to fusebox

Thanks Jerry! U just saved me 150 bucks on my jeep. Do you remove them in the winter when voltage is higher or just leave them?
Thinking of doing this to my Jeep
I just want to know where this wire is on my camry. I have a 240 amp js alt. I don't have an external voltage regulator.
what year is the camry
I can set you up with variable voltage. Super easy.
@Rowboyto just now seeing this. It was a 12 camry. I ended up replacing my underhood "alt-s" fuse with diode fuse and it did the same thing. I now have a 21 camry which uses LIN so now I have a different setup.

Can you do this with a Lead flooded battery or only agm battery
Can you make a video more in death how you put the diodes on a certain wire?.
Watch it again, he tells you several times, the sense wire..one that stays hot all the time

@Jerry Aintloud yeah I found it, thanks man! I'm charging 14.2 and needing 14.8. Prob only need 1 diode.
What color is the sensor wire I have the same car
Can you use diodes on the jeep or would I need a external regulator? Because the jeep has a pcm controlled voltage?
I use a external regulator that's adjustaboe. it's a lot better to do it external.
@@JerryAintloud alright thanks👍

Can't you just use a fuse style diode and use it on the "charge" fuse in your fuse box?
Can u put a link in to the diodes so we know which ones to buy,please

Do you know if this will work on a 2004 jeep wrangler alternator ? or does the computer keep that from happening ?
I’m wondering the same
Does this increase amperage😊
When you say "sense" wire are you referring to the stator wore labeled "S" on the alternator?
yes
So does your Ford Edge have bms on it
Do you know of any other diodes to use other than 1N4004 because 2 diodes is putting my charging as high as 16.4 at times. Usually 16.0 but sometimes I'll see 16.4 and my radio doesn't like it and neither do my gauges in my truck.
so remove one. If 2 diodes is too many then use one.
Couldnt you make links like you just did for individual diodes that plug and play like yours just did but solider the diods to the connector. This would also mean if one died you could easily remove it and continue.
Its the: 1n4001 1 amp 50v rectifier right? I'm just making sure cuz it look like your bag info said 1n4004 and thats the 1 amp 400v version lol
Awesome eff a hi output..
I have a mitsubishi endeavor how many u suggest?
3.5 or 3.8L? You can use aftermaket V6 eclipse and 3000GT alts, 72,74&75/m all have the same accessories
I've got a 75 swapped AWD diamante here in Australia and have done my homework on stereo options for Mitsubishi
Curious if I got an AGM under the hood, can I put a lithium in the trunk on a battery isolator?
I would just put a distro block under the hood and run all lithium. I ran on an isolator for a year and had nothing but issues. When I finally took my AGM out the system was so much more solid.
Can I do that on a suburban or Tahoe?
thanks for the info
I have an ebike
How many of these would you need in series to reach 42v?
it doesn’t work like that, you would need to change battery config, for instance, building a panasonic cmax/insight bank in a 12s3p config would give you a 15ah 44.4v lithium bank that should work for your ebike. but it would be a big and bulky bank as you would need a bms for balancing, overcharging and undercharging protection and most importantly, compression for the cells as charging can cause them to swell.
Will this help my equinox pcm controlled voltage issue?
Dont think it will no. Think you need a bypass.
sense wire = excitation cable?
Are the right diodes 1N4001 or 1N4004? Does it matter?
Either,ypu can go up to N1007
So I have a 2014 Ford edge is there a way to hook it up to where my battery light doesn’t come on with the high alternator
And the PCM bypass
I have a 2014 Ford edge what color is a sensor wire or how to do this
Is that stock alt
What harness do you need for the diodes?.
He said the sense wire that plugs into the alternator (one of the thin gauge wires).
Can you lower the voltage with diodes also?
Resistor would drop the voltage
16V how does the car 12V electrical react to this ? ( assuming the 4 series diodes are on the 12V alt and not a 14V alt for car audio only )
the car does fine up to 16v over 16v random warning lights come on
How do you no if a diodes has went out
Can I add to a stock alt?
Can i add diodes to my 2006 honda civic?

07 Tahoe
Do these help with voltage drop?
No just to raise voltage
Each 1 causes a 0.7V drop as current flows... how it is increasing voltage seems intriguing... :-/
@REG3305 it's telling the alternator that the battery is low and needs to charge. The more diodes you add. The more the alternator charges bc your battery tells the alt that its lower than what it actually is.
Is bad to be running at 16v like as far as the ECM and tcm
my jeep loves it, this car gets a lot of warning lights in the dash at 16v. but otherwise everything is fine.
14.4 v is safer
Shit, can I do this to a stock alternator?
Is there any downside to doing this?
