A/C only works on accessory
Hi everyone, need some help. All of sudden, my a.c. only works in my 83 911 sc when the key is turned to accessory. When I start the car, the a.c. stops completely. Turn off the engine, put the key in accessory, and it works again. Diagram shows that the ground wire (yellow) for the smugglers box relay goes to the starter!? Can anyone explain the reason for that to me, please? Problem seems to be that yellow ground wire, as when I ground the wire out, a.c. works fine. Does the starter provide a ground when the engine is running? I don't remember the a.c. working on accessory before. Thanks!
