I give up. I don't understand the wiring of the turn signal dash indicator lights on this car. When I got the car the PO had installed a new wiring harness during the restoration. It appears to be factory correct, it has the right color codes. The PO had never been able to get his signals to work. I discovered the running light and turn signal wires were interconnected on the terminal block in front of the radiator. I corrected that wiring and the signals on all four corners of the car started working properly. Then I noticed that the dash indicators both blinked regardless of which directional signal was on. One is at full brightness and the other is only slightly dimmer. My first thought was insufficient ground to the bulb sockets in the dash so I pulled them out and applied a direct ground using a jumper wire off the battery positive, no change in operation. Then I started looking at how the wiring is connected to the sockets.
There is a black wire that would feed the center post of each bulb. Then there is a green/white wire connected to the body of one socket and a brown/white wire that connects to the body of the other. Apparently this is the same green/white and brown/white wires that go the front signal lamps. I am having a hard time understanding how this can work. The socket body plug / snaps into the metal dash which is grounded. How can a signal wire connect to the socket body if the socket body is being plugged into the grounded dash? Is this the way the wiring is supposed to be or did the harness manufacturer screw up when they attached the wires to these sockets?
If this is how it is supposed to be can someone please explain this circuit to me.
