Voltage Problem
Hey Guys. I got a 98 GT and recently the voltage gauge in the gauge cluster has been reading lower than regular. It usually sits between R and M in NORMAL. Now it has been between O and R. I tested the battery at idle ( approx 750rpms) and got 12.4 volts. Then tested the alternator at idle and got a solid 14.2 volts. I was wondering if it could be the voltage regulator on the alternator that could be causing this problem. Any input would be great. Thanks

RE: Voltage Problem
so at the battery your getting 12.4 with it running and at the alternator positive post it was getting 14??? sounds like a problem between the alternator and battery. a bad battery could cause it too, but it probably wouldnt start.
