Fuses or Circuit Breakers

[dubnali]

Just bought a 1972 M35A2 and have electrical issues. The only thing that works is the lights. Can't find a fuse panel. Are they all breakers? Is there a main supply point for these things. Has a cab heater, blower won't run. Has been upgraded to electric wipers. Neither work.
Any help would be greatly appreciated. Thanks.

Circuit breakers, but they are self resetting go to TM9-2320-209-10-3.pdf and start the fun. If you can get a hold of the previous owner he might be able to help. Added the schematic that will help you trouble shoot. They look like this and with a heater should have 2 on the driver side fire wall.

FYI: The only fuse on an A2 is on top of the fuel tank, for the in-tank fuel pump. The circuit breaker/s is/are located on the engine side of the firewall, just above the steering column.

1. Do a search for fuses or circuit breakers and you'll see that fact that the deuce only has one fuse (on the fuel pump) and one circuit breaker (horn I think) many times.

2. Do a search for "Peter Bog's Deuce Schematic" and you'll find a super nifty wiring diagram done in CAD.

3. I'd say since your lights work but nothing else that there is an issue with the main power switch (top of the dash, above the headlight switch). Find the schematic, get your multimeter out and see if it has power coming in and power out when the switch is on.

4. Good luck.

Sometimes the heater circuit breaker can be found mounted behind the dash, between the steering column and the windshield wiper valve.
