It sounds like the gauges have a bad ground. check to see if the connections are all tight. On some cars the bolts that hold in the gauges are the ground.

also it only happens when the car is runnung a while and at a stop with the car in drive... I have had an aftermarket stereo installed for years never any problems... the voltage is actually dropping because the amp shuts down ... I did disconnect the amp and no change .. I shut the a/c when the volts drop and no change ... it is baffling I hope it is the ground as you think...

I think it has to do with te cooling fans when they click on the voltage drops... are they expensive to replace???
