When my 1991 Z28 gets up to temperature the volts showing on the volmeter go down. When I hit the brakes it moves down more, and even more with the blinker and the brakes on. The needle moves to the blinking of the blinker. Volts are dropping way below 14 on the gauge. I have takin the fuses out for the heater/ac, the stereo, and the lights. Nothing seems to make it better. After about 30 mins of driving in town the alternator is hotter than the engine. It runs just fine on the highway no problems. After 2hrs of highway driving I can still put my hand on the alternator. I have replaced the alternator and my battery still has the green eye. Does anyone know what could be causing this????
