Wiring for the 12v system is probably similar to a GX390 and schematics for that are easy to find.

Google Honda GX 390 wiring diagram. If you wish to increase the charging output get the Honda Charging coils, they are much bigger. They will require a tad longer mounting bolts and a regulator. Pretty simple.

I can probably answer the question your needing also ? I completely rewired both of mine to delete the oem switch box.

Not certain, but probably 4-5 amps. Probably plenty to keep the battery charged. I think my regulator/rectifier took a dump on mine though. I intent to put a John Deere type 20 amp permanent magnet unit on mine. I already built a pulley that sits behind the driver unit of my 40 series TAV.

I am considering the same thing... but I believe I'm going to go with a mini denso 30A. I'd be interested in hearing what you did for a pulley behind the driver.

Tractor Supply sells weld on pulleys. You buy the pulley you want then a hub for your shaft. I bought a 4” pulley for a 1/2” belt. Instead of a hub I got a shaft collar which was real close to fitting in a pulley. I spun the collar in my drill press and used a file to take it down the tiny amount needed. Welded it up. It runs straight and true. Can’t really get a key in it that close to the engine. And although I thing the TAV tightened down will hold it I still filed down a set screw that fits in the keyway. It’s going nowhere. I have the power sports TAV and it requires quite a few flat washers to set up correctly. I only used a couple thin flats and the pulley is the rest.
