- The electric starter kits you can buy from eBay or elsewhere do not come with any install instructions or wiring diagrams. You need this video to understand or to make modifications.

No one that sells these kits includes instructions or wiring diagrams. My Honda GX390 came pull-start only and after a shoulder injury I couldn't start it anymore. So I bought a charging/starter kit with a dual timing starter flywheel, two single wire A/C charging coils, and an off-the-shelf voltage regulator / rectifier and installed it all which is so easy that a 5 y.o. can do it, blindfolded. Seeing that the two single wire A/C charging coils could not attain more than 12.3 VDC for battery charging, I just finished swapping them out with larger A/C charging coils with two wires each coil that is supposed to output 120-watt / 10 amp. Tomorrow after the rain passes, I'll take it outside to fire it up and see if larger coils output at least 13.4 VDC or more to the 220 ah garden tractor battery. There is a full-wave 3 phase kit for small engines but it is very expensive.
Thank you, very detailed! I have been looking for a while on how to wire this kit , I was completely clueless. This video has been of tremendous help.
You're welcome! I enjoyed learning this info with my dad, and glad I was able to share.
@@greenlizardusa3105 wait, did you just say the extra white wire provides 12v of power? So I can attach a 12v fan to cool the engine? It would be nice if you can show that on video!
The white wire that comes from the generator coil and goes through the resistor and into the ignition housing is supposed to be wired in with the positive that runs back to your battery to charge your battery that starts the engine. Now whether it is wired up like that idk.
That is 100% correct
Looking to install key start on my FIL wood chipper since he can’t pull start. Thanks for the info!!
The Most important part of a step by step connecting every wire You did not do Just showed after all wires already connected at the end MAKE IT SIMPLE JUST SHOW EVERY WIRE CONNECTION . to much BS on wire diagram and never showed you connecting every wire to what goes ware.
Thank you ,that's what I was gonna say
You are not grasping the components and function of the charging system. The charging coil that you had in your hand does function with the magnets inside of the flywheel as you described on the whiteboard. The voltage that you measured when it was running was AC voltage. All small engine charging systems using a coil and magnet combination produce AC voltage out of the windings. Then there are various ways to convert that AC voltage to DC voltage in order to charge the battery.
The white wire on the key switch panel that you had in your hand at 7:50 in the video is supposed to be connected to the wire coming from the charging coil. If you looked just to the right of where you were holding that wire with your left hand, where the black heat shrink starts, there is a bulge underneath the heat shrink. That is a diode. It only allows electricity to flow in one direction through it, basically like an electrical check valve, and serves the function of converting the AC output of the charging coil to DC. It does that by effectively cutting off one half of the AC wave. It is generally called a half wave rectifier when a diode is used in that fashion. This is the most basic method employed to convert AC voltage to DC.
So if you put the charging coil in place and connect the bullet connector together, when the engine is running the AC voltage will go through the diode, be converted to DC, then run through the key switch back down to the wire going to the starter terminal and through the red wire back to the battery and recharge the battery when the engine is running.
Now, for electrical protection there should be either a circuit breaker or fuse in that line from the key switch panel to the starter terminal. Not sure why Predator no longer has that circuit breaker in there, perhaps they incorporated a breaker or fuse somewhere up by the key switch under that cover. You could always go to the auto parts store and just get a fuse holder and put it in the line going to the starter terminal from the key switch.
You're missing the opportunity to keep your battery charged and you could always wire in 12 volt lights or a phone charger, etc. to your battery.
Thanks for the detailed comments byronmill! It's been a while since I worked on that project, I'll have to revisit it and look again. Super helpful, thank you!
I have that exact kit and it came with a breaker switch where that button goes, his kit must of had someone forget to add that to the kit when it was assembled.
Great video thanks man this was super helpful!
That would work if you had a picture of diagram so we can read what your saying cause no colors or hooking up to switch
I'm not sure what i have going on with mine, as soon as i connect the battery even with the key in the off position, It smokes the ignition coil. Any thoughts ?
Could you tell us where each color wire from the starter switch went?
Sure thing, I'll go out and take a look and write it here in the comments.
So?
Did he come back inside yet?
And still does not show what colour wires go where so what’s the point.
How do you add a voltage regulator to charge a battery? In my kit I added a voltage regulator so it'll keep my battery topped up. Can you show me how it would be added into the diagram? Btw, I just sub'd too! 🤘😁
Anybody know if these kits will fit in the new 224 engines?
hello i have 11 hp engine i have two yellow wires coming from carburetor! where should i connect them?
Ummm where does the black wire from the starter solenoid go too
But how do wire it up??
I agree. I know how many wires it has placing them is the issue changing from rope pull to electric. He has the exact switch. Even the black split wire . Helpful would have been to do 3D as in show connecting switch wires -- to GX390.
2 questions - 1. do the gears on the starter push out to engage the flywheel? I'm having trouble because the gears on mine are not engaging the flywheel and i cannot figure out why. The gear spins but doesn't come out to engage. I thought maybe I had a faulty starter but ordered another one, which did the same thing. Maybe I got two faulty starters but chances are I'm doing something wrong. Question 2 - the wire from the generator, can that be connected back to the battery to charge it? If yes how is that done? does it connect to the positive or negative to charge the battery? Thx.
Charging goes to positive, and your starter solenoid is what moves the starter gear to engage. It sounds like you never wired the solenoid, or the coil that magnetizes it is burned, unlikely, on a new starter. Connect the solenoid to the start circuit, so, when power goes to the motor, it also engages the solenoid. Just make sure it disengages, and backs out after starting, or the starter will be wrecked. Maybe find a back yard mechanic, for some guidance. Hope this helps.
sooo where do i get all of this?
Mine has a BROWN wire coming off the Circuit breaker where the heck does that go
What size battery should and or would power this?
I was using a large marine deep cell battery. Walmart special:) I'll check specs on it tonight.
@@greenlizardusa3105 Alright, thank you!
I was able to get mine to start with a power wheels battery, I would imagine a motorcycle battery will work as well
@@mexalejo Oh ok, do you happen to know how many volts and amps, or I could just buy a power wheels battery because I could then recharge it 🤔
@@mexalejo or could I just use a drill battery? Because I could use an adapter and recharge it
4.06 i believe thats wrong you show a ground coming off generator coil going downward on your drawing that operates the spark plug ,it should have only one ground and thats thru the off switch
you show a total of 7 grounds from left to right ground number 3 should not be used
You can use the charge coil to charge your battery bud 😂
Can you do a basic video no extra talk please just this wire goes here and so on...
Lol bruh
That's a good idea. I'll see what I can do!
Was trying to find yellow with green stripe but he just went on and installed without showing the proper connections
