My 1980 F350 died while plowing snow. It happened when lowering the blade. No electricity inside, no horn, no start, no wipers, no lights, no fan.
Battery shows 12.5 volts. Checked ground to chassis and engine, has voltage to alternator main terminal, the black wire at the front of the starter relay (fusible loop?) has power both sides of red tab. I checked fuses with flashlite, all look good, but haven't removed them yet, it's 15 degrees outside.
Is there some kind of main breaker somewhere that feeds everything going to the ignition switch? Where should I look?
4x4 with 460 engine (installed by previous owner) and C6 automatic.

 

There are several fuse links off the solenoid. probably one is blown
Best to just tug on them, they will stretch when they are blown
