Greetings, all. I have a 1971 Plymouth Sport Fury with the Lock Doors light as part of the ignition key and instrument cluster floodlight illumination circuit. They did work a few times for me, but now none are lighting. I am getting power to the "hot at all times" terminal of the relay, but how do I test the rest of the circuit? The service manual doesn't seem to do any more than show a schematic or two. I'm not fully convinced the relay is actually bad. Also, can I still get the relay from Chrysler? (I think its part # 2889565) Thanks a lot!
