Hey all, I'm having an issue with my '86 headlights. The passenger side low beam has 12V to the lamp, but does'nt work.(yes the lamp is good) The high beam works. When testing the socket, found that the high beam has continuity w/ ground. Driver side tests fine. Fuses are good. Disconnected high beam from socket and still does not light, even when 12v is present at socket and making good connection. What am I missing here? Tried tracing wires through harness but unsuccessful.
