Was wondering if anyone knows what the voltage stabilizer looks like. Is this built in the alternator? or a seperate component. I have 3 or 4 terminals coming from my alternator, so maybe looking there or is this in the dash? I'll have to check voltages coming from the alternator when I get a chance.
Thanks

The voltage stabilizer (regulator) is inside the alternator, If it is an OEM or identical substitute for the OEM alternator.

13.8-14.5 volts is normal for alternator output. Turn all the electrical accessories on while you do it. This will help see if it is doing it's job.
