Where would the voltage regulator be located on a 90 SSE? I cant seem to find it in the FSM..
I'm starting to think that my voltage regulator is having problems, since I've not fried 2 Twilight Sentinal modules in my car, my power seats and power doorlocks aren't working still...

It'* built into the alt. When my twilight sentinel module fried I just unplugged it & turned them on & off manually. It sure looked like a fire hazard to me.

Regulator is built into the alternator attached to the rectifier.
If it went the car wouldn't charge at all or it would overcharge the batt.
