High voltage

hey all, i have a 1986 9000 turbo and i am having troubles with it runnning at high voltage. When it idles it is at about 12.5 volts but when driving i am at around 19 to 19.5 volts. Not sure if its mt alternator going bad or voltage regulator or something. Hope one of you will have some answers for me. Thanks!

RE: High voltage

voltage regulator I think...go to advance auto parts, they do electrical system checks...

RE: High voltage

well i got the voltage regulator replaces and running well now. But, when i was running at 19 volts my heater blower quit working. Does anyone know if there is a blower motor relay somewhere.

RE: High voltage

I would say that you fried the resistor that controlls fan speed. Not sure where it is on your car though...
