I think I may have found what has been causing my electrical problem
I've been getting all 8 glowplug codes on startup, my battery voltage on my Insight CTS has been wildly fluctuating, sometimes even dropping in the low 12s and high 11s. But when I hook up a voltmeter I'll get a good voltage at the alternator 13.8-14 no matter what and at the batteries will just be a bit lower than that at 13.3-13.5 and only around 13 on my Insight, but it jumps all over the place varying 1 to 1.5 volts.
So I saw a cable going from the positive side of the passenger battery and noticed it had a small chafe on it. I wiggled it around and noticed the voltage on the batteries jump up! So I pushed it in and the battery voltage jumped up to nearly exactly what the alternator voltage was and my Insight was showing only .1 volts under that and it was stable.
Apparently this cable is coming from the alternator? Is it something that I will be able to fix myself or is it something inexpensive and easy to replace?
