Help! Last Friday night as I prepared to go to a show I had a bit of an
electrical fire under the dashboard and hood of my M62 wrecker. After
discharging to fire extinguishers and disconnectiong the batteries I was able
to extinguish the fire. Incredibly, after taking the wire cutters to the
burnt wires the truck functioned almost normally. Today I began trying to
make repairs, this being complicated by the number of field modifications the
truck got over the years.
They are:
Rotating beacon---no longer works.
two warning lights on front fenders (NOT turn signals), one of these field
modification, one factory---don't work wires cut by US at some time ago and
switch removed
Heater blower motor---doesn't run---wires intact through firewall, then?
fuel gauge---after fire pegged way beyond full
floodlights don't work---never have since I owned truck, the dash switch
which should have controlled them, instead controlled aforementioned beacon.

Two wires running to floodlight switch burned to crisp, one wire going from
main wiring harness to ? (circuit breaker?) burned and annealed.

The truck had a new harness installed by military at some point. Truck
tagged rebuilt at Letterkenny in 67, but harness has rubber type connectors
rather than metal shell type, this and the 1700 miles on the clock when I got
it along with the overall OUTSTANDING mechanical condition of the truck make
me believe it got another overhaul at some point. But the rubber connections
are more or less taped in the big openings of the circuit breakers, where the
big metal connectors would go. Has alternator, not generator.

My point is anybody know where I can find schematic for M62 on web? How
about ANY G744 schematic? Anybody got an M62 in the back yard I can get to
compare notes with? Anybody got first hand experience with any of these
modifications or repairs?

I have TM9-2320-211-10 and TM9-2320-211-20 and these are NO help on this.

Sorry for so long but wanted to give as complete info on problem as possible.

Thanks,
David
