Yes, a newbie here.
Let me start off by saying I have read most, if not all, the threads related to my problem and am still stuck.
I have 1972 521 with partial working dash lights. The red ignition light works when I turn the key one click, then the light turns off when the truck starts.The left and right turn-signal lights on the dash match the flash of the outside turn signal lights. The headlights work low and high, and the red light to indicate brights are on works. When the the hazard light switch is pulled, only the left side flashes on the dash and on the truck (confusing!). The fuel and temp gauges work.
The problem is I have no instrument lights working to drive at night. I have cleaned the all contacts; I checked all bulbs, fuses, and relays, and all are working. I also looked for dead spots on back of dash panel.
