I need help with my 1978 Honda Express-NC50 electrical system. My battery will not remain charged, only does for a short time after a full charge.

On a full charge everything works, then within minutes the horn and tail-light will stop working. The battery gets warm, as does the rectifier.

If I disconnect the battery, the voltage goes to 12 volts-burning out all bulbs. The bike of course will still run as normal.

I've tried other (same type ) rectifiers, no dice.

Any advice will be super appreciated.

Thanks, Gary
