|
|
So today I started my vw thing's engine for first time after re-installing it. I started it today and it ran the battery down and died. My gen. idiot light comes on when the key is turned on. It goes off when running, making me think it was functional. Anybody have any insight on what could cause this? |

alright, so I just tried to polarize the generator. When I touched the power wire, it spun for like 1 second then stopped. now it won't spin anymore by doing this. Does this mean its bad or could something else have happened? |

yep. I think it came down to the wiring. while further testing, I noticed the spot where my ground connects to body from battery was throwing sparks, meaning it had bad connection. I cleaned up both the wire and the mounting point, and hooked it back up. did a test run, no sparks and my multimeter showed an increasing voltage at battery once it was running, showing that my generator was indeed charging the battery. within couple minutes it went from 12.6 to 14.3. This seems to be symptoms of a good charging system? |

I always run extra grounds you can't have too many grounds remember you are driving a over 40 year old pile of rust with paint making it look good or not. |
