I have a 90' 318 with a GX620 Honda repower and recently it has quit charging the battery. I checked voltage with it running and it doesn't increase ,leading me to the charging issue. Any help you can give me on this would be appreciated. Thanks

You are doing the test right. Typically garden tractor charge coils will put out somewhere above 28vac. However being a repower you don't know what is in it. But we do know the 318 needs more than its putting out. Cast into the side of the block is the model number and serial number. If you take those numbers into a Honda dealer they should be able to get you a charge coil and voltage regulator with the out put you need.
A possible theory is that the original Honda charge coil was too small and the 318 ran it at its limit until it burnt out.
It would be handy if a 318 expert could chime in with the 318 onan amp spec.
