Hey guys ive been having an issue with my charging system.the other day I was driving and my check gauges light came on and my voltage gauge went all the way down. But nothing was going wrong except that. Every time I would shut it off and start it back up the gauge would start at 14 then after a minute or so of driving it would happen again. Finally 2 days ago it went for good and I had to jump it and limp it home... ive since went and got the alternator rebuilt and for the first day after that it was fine. Then yesterday I was driving for about the first minute again and the check gauges light came back on and the voltage gauge dropped all the way down again. Does anyone have any idea what could be wrong now

I would suspect wiring or a loose connection to the battery. At least those are easy to check and free.

Could also be a bad ground as well.
