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

When it was repowered, did you retain the original regulator or ???
Need more info/wireing data to help.
It would have been on the Onan. Could have been relocated anywhere, or replaced with a different reg. You are going to have to chase the wiring down. Should be two wires coming from under the flywheel to wherever it is located. Check the voltage at those, disconnected and engine running. It will be AC and probably over 28v at half throttle.

If you have that, it's likely the reg.
