The only remote chance that I'm thinking is that the alternator burnt badly and prevented rotation, which in turn prevented the water pump to move. Very hypothetical...
Please check if you can rotate by hand your alternator and the condition of the belt. I'm thinking that the alternator burnt. The short was created inside, and fried the cables that you reported.
I have checked out the alternator and it is not seized up. the belt looks good but has some play, perhaps if it was slipping and could have created the over heating problem?? I had to remove the heater core when I first got it home because it was leaking badly, I bypassed the heater by tying the inlet and the outlet together. I didn't think this would effect engine cooling by much. Did I miss something there? Is that little heater core that important as a heat exchanger?
No, the heater core isn't necessary for engine cooling. Some Patrols don't even have a heater. But, for a Patrol to overheat is pretty unusual. With the huge 4 row radiator core the usually run pretty cool. Unless something is seriously wrong.

I plan to do a flush and leak check of the radiator. Any other tricks or tests?
One thing to check is blockage in the engine block. There is a petcock on the engine above the starter where the rear heater hose connects to the engine. Many times there is sludge build up there. Remove the petcock and fish a coat hanger into the passage and see if it clear. If not, use the coat hanger to dig out or free up the gunk in there. Disconnect the lower radiator hose from the engine and try to flush water through with high pressure.
