76' 620: Fuse blows
Posted 17 November 2017 - 03:01 PM
I have :
- Disconnected the regulator to test if that is the issue
- Disconnected the dimmer switch
- Pulled the entire gauge cluster out
- Replaced the entire fuse box with a new box
- Disconnected the engine bay inspection light
- Disconnected the 10 pin connector from the main harness to the cabin and back wires to isolate the tail lights and cabin accessories.
Things to note:
- My reverse is not hooked up
- The only aftermarket accessories are a tachometer and a electric fan, but the power and switches are either off the battery or resistor.

You have a short to ground. Check for continuity through the connections. Find where you get no current flow.

Reverse lights might not be hooked up, but where does the wires to the switch on the transmission go? I had constant blown fuses on that circuit on my '76 KC- turned out the reverse switch wires had rubbed the insulation off on the torsion bar and were shorting out.
Well, at least he gets 24 hours notice. That's more than most of us get. All most of us get is, "Mind that bus!" "What bus?" _splat_!

Try unplugging the 4 way emergency flasher also.
If you have an automatic, unplug the kick down switch on the gas pedal.

Agreed. I often modify the title to make it more relevant than "Help!". This post could save someone else a lot of bother.
