I don't have any dash, tail, or marker lights. I have checked all fuses and they are good. I am taking it to an electric shop next week. If anyone has experienced this before and knows a cure it might save me some money. Thanks
I would recommend getting a six pack and a Mitchell Systems manual.
Next, I would look into your grounds for your dash and lamp harness. I had a bad connection at a turn signal / marker light that bled current back through my turn signal indicator on the dash. It took me a while to figure it out... make no mistake -IT DROVE ME NUTS!
You have to remember that these harnesses are getting old. Tired reflects the condition of the wires and plastic connectors. 737s are about as old and they have had their harnesses replaced several times over!
