I dont have lights, windshield wipers,ac or heat and the blower motor doesnt come on at any speed. Any ideas?
fuse
has any work been done lately or is this really an "I was just driving along" issue?
Your main power relay is burnt, and or your diodes under the cab have corrosion and failed. Inspect your relays. You can jump the main relay to get the machine going. Tilt the cab, left side of machine, inline in the harness is 4 diodes. 3 are grouped together, and one is about 5" in front of the others. They are usually rotten and green with corrosion.
I'm also having this same issue. With machine running should I have power at all four diode wires?
