2001 "parts motor" I just picked up. I fired it up with the rope and it ran good. Then found out it can damage the charging system running it without the batt. There is nothing plugged into the wiring harness connector if this helps [ remote control motor ]. I just hooked up a batt and it's not charging. Does the remote controls have to be plugged in or did I fry something ?<br /><br />Can someone shed some light or tell me how to trouble shoot? I have a good multi meter.
