So after cleaning up the rear wiring a bit I've found an odd issue. I've cleaned and checked the body harness, grounds test good, positive 12v feed for the socket tests good. Socket and bulb hooked up to a 12v battery directly tests good. The issue occurs when I hook the 12v feed to the socket. Detatched or without a bulb in the socket I get a solid 12v reading on a volt meter. With the hazards or turn signal on I get a 12v pulse. With the bulb in socket voltage drops to .2 or 0. I've gone over everything I can think of and haven't found anything causing the drop. Anyone run across this issue before or have any idea what it could be?
