So it seems like I am loosing voltage as the car gets up to temp. I am having a few issues with voltage loss and I am wondering if any of you have dealt with something like this? I just replaces my alternator with a new 150 amp 1 wire because I thought my old 110 amp was failing when it got hot. When the car gets hot the idle gets iratic and you can see the voltage gauge drop in the car on the gauge. However the alternator is still putting out 14 plus volts. I removed the original voltage regulator some years back. The Distributor is a new DUI unit. Most everything else is stock stuff. So I am scratching my head wondering what could be causing this voltage drop as the car gets hot? I am gona start chasing wires around tomarrow and do a bunch of checks for voltage as the wires travel threw the harness tomorrow. Just hopping maybe someone has dealt with something similar and can point me in a direction? Thanks guys.
