Hello all.
My 1991 alfa spider has an issue. The alternator only produces 12 volts (battery connected or not, no difference). I have changed the regulator with same result. Do you guys/girls think it is the laternator itself or wiring issues.
Also, the fans are always on and the temp sensor on the radiator is new. It is probably the AC switches, but I do not know where they are.

Any help is appreciated.

problem solved

Hi Resqguy.

Thanks for the reply.
You are right about improper fixes.
The previous owner had wired the cooling fans directly to switched 12 volts which were bringing the measured voltage down to 12 volts. Once I rewired the fans correctly, the alternator is showing 13.5 ish volts, which is good.
thanks again.
Boris
