Good morning from Alaska!
I've acquired a 2000 M1078A1, learning as I go... after completing the services, filters and all of the fluids since the Army drained everything, this machine pops the CB77 fuse every time I flip the power switch.
Fuse block and cover appear to match, the blown CB77 fuse that came with this machine was a 20a. I've swapped out all of the resettable fuses that failed with standard blade fuses. the fuse box cover says the CB77 should be a 10a. that had me a little concerned right away...
so far, we've isolated the starter relay, completely removed it and still pops the fuse. if I jump the relay, the starter engages and spins the motor but won't start since the Cat computer isnt on.
I've isolated the air heater grid, still pops the fuse. And we've isolated and bypassed the Pac Brake solenoid, still pops the fuse.
Next, I downloaded the manuals, but I'm running in to a wall... I think the TM manual I found is for an older unit, we went through the electrical steps til it calls for testing K24 relay. My LMTV doesn't have a K24 relay, unless there is another panel that I haven't found yet.
Any ideas?
