Hi, I have a 1982 300TD. I am experiencing some strange instrument cluster behavior and I'm wondering if someone might chime in on how to fix it. I've removed the cluster a few times to make sure that all connections are sound and as far as I can tell, they are. Quite randomly, the fuel gauge and the temperature gauge start to jump a bit. If I switch the headlights on, the fuel and temperature needles get more jumpy, the buzzer goes on and off and the instrument cluster light turns off. The pressure gauge and others work as expected though I have to use a flashlight to see it. Thanks!
