Voltage Issue: Need opinions.

[Matts94Z28]

Back in 2007 I went through a TON of alternators with my car, I just couldn't find a delco that worked right. I finally found a local place who rebuilds starters and alternators and had them rebuild a delco for me.

Fast forward

Last week I noticed my car wasnt charging as much as it normally does and it progressively got worse. It finally got to the point to where my voltage needle was dipping into the red on the stock gauge.

I had the same place rebuild my alternator and put it back on the car today. I went out in the car tonight and had no isseues until I went to leave SSS... CLICK CLICK CLICK... I originally thought the battery had died. Brandon and I figured that the battery had plenty of juice and the connections were tight so we moved on to the starter after he though he saw an arch.

It turns out that I had to jiggle the connections at the starter to get it to crank... it fired right up. Well on the way home I noticed the volts were low again... WTF?!!!?

Do you guys think there could be a short in the positive cable that runs from the battery to the alternator/starter and COULD this possible cause an issue with the low voltage if it were truely arching off of something while running?

Oh and another thing, I think the alternator might have been fine all along, because when I picked it up the guy said the regulator was bad and the volts shot up to 20 on his bench... I call BS because it sure wasn't doing that in my car... I think they took me for the money... but hell, I have a fresh part now.

Thoughts?
