Hey guys,
This question is about my 1974 Mustang 2 Mach 1, but it is nearly the same car, at least in my humble opinion. ;-)
So I start the car up, without any electronics running, and I run at 13-14 volts. But as soon as I step on the brakes or turn on the lights, and I am sure use the wipers or turn on the heater, the voltage jumps up to 16+ volts.
POSSIBLE ISSUES:
Voltage regulator...
Alternator...
A short in the wiring...
Please give me some ideas and replacement plans...
Thanks,
Shane
