Hey everyone. I got this 81 pa50ii, completely original, hasn't ran in yyyyyears, but appears they drained the tank before letting it sit. It was missing the battery, I installed the little jumper wire, threw some gas in it and pedaled my ass off and it runs!!! My problem is that it blew the headlight taillight and hi beam indicator within less than a minute of running. I think in mb5, so am I wrong in assuming that without a battery, the ac ripples overload and blow the bulbs? Is there an oem voltage regulator, diode, or something like that, that I could check?
