1984 190e voltage reg

I've replaced my alt 2 times. As soon as I restart the car the voltage regulator shorts out.

Your alternator diodes must be shot. Perhaps the battery was hooked up backwards. Also, check the fuse on the OVP, the can with the red top.

OVP = Overvoltage Protection Relay.

Take the alt to a shop to have it checked.

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant

thanks for the reply. I've put in a second alt now. battery is hooked up right it blew the voltage reg as soon as i started to car. Seems it must be that fuse OVP thats got to be it. I will have a look at it today. I just pulled that OVP and the car wouldn't start without it. the small 3amp fuse on top of it is OK.
