Re: 2000 Chevy Express 3500 alternator/battery issue (possibly grounding?)
- Battery was slowly losing power (wouldn't start as well over time) so I replaced the alternator.
- Refurbished alternator in, no power at all.
- Find out my battery was actually bad, so i put a new battery in.
- Van starts but for the first time ever the battery light is on and stays on the entire time I drive, dash is only showing 9 or less volts
- Battery drains, van dies, get battery charged and take it to autozone to check the alternator, alternator is completely dead.
- I now have a brand new alternator and a fully charged battery but I've been warned to check all my grounds as that could allegedly be the source of this tail chasing problem.
I've been told this could be a grounding issue, but It could also just be a very unfortunate series of events with getting a bad alternator and all... its hard to say at this point. I just want to make sure all my grounds are good so If anyone knows what all ground points I should check I would be eternally grateful.
Thanks!
