Hi my name is Robert...

What I would do is go to the chassis battery and follow that cable to the fuse box, look for a tripped breaker, below is a picture. Most have a tiny tab on them that pops out when they trip, as a general rule it would be 18" from the battery and can be on the frame or inside a battery control box with other fuses and breakers. IF you can jump the fuse block then it has to be between the battery and that fuse block. IF you have a chassis battery disconnect switch inside please let me know. Some will have one for the chassis battery and others do not or will have a manual switch right near the battery.... Hope this helps some, IF you have more questions or concerns please feel free to contact me.... Robert
