No, I was just curious if he had solved is problem. I like those weird problems.

Did you find your problem??

Manual says it can go up to 15.5v to charges the battery. 🤷‍♂️

Battery is good so is the stator, if I probe the red wire at the regulators I get 14v, the regulator does it job but it doesn't go to the battery for some reason. The manual doesn't mention nothing about the diode and the capacitor for the recoil, it's hard to diagnose without proper documentation!

Ok, I'm at a loss, did a wrong call on the regulator because of the lack of info in the manual. The suspected culprit was the rectifier(diode) that is inline on the red wire coming from the regulator/rectifier to the battery, if connected the battery does not charge if bypassed the battery charge. We ordered a new rectifier(diode), with the new rectifier the battery still doesn't charge!!!

Yes.

And because of their screw up I made a wrong call on a regulator!!

For the part you will need your serial number if your bike has one. Number for the kit 08U78-HP7-100 Remember this post https://www.hondaatvforums.net/threads/2013-honda-rancher-420fm-electrical-problem.125374/

It's part of the recoil starter kit.

If this thing goes south the bike will not charge, I've messed up my diagnostic because of that and the manual has no mention of it.

Yes it's no.37, my dealer confirmed me it's a diode (RECTIFIER ASSY.), part number 31710-hp5-651.

Anybody knows what part this is? The manual doesn't mention it, the wiring diagrams don't show the part and the online parts fiche shows the part but no reference to it! A diode?? The part is between the regulator/rectifier and battery on a 2009 420 FPM. The ATV won't charge with it plugged in, if I bypass it the battery charged.

Or when they bring their atv with no gas in it and complaint it doesn't start..."Does not start I had to push it in the truck!!!"....🤣🤣

😂..Did that too not to long ago, I hate it when the starter turn with the kill switch off!! The kill switch should kill the engine and starter!

Your welcome, great community and great people in this forum, looking forward for my next diagnostic!
