Cat 345BL blowing 10 amp key switch fuse

FredMcAlister ยท 2021-11-06 20:13

Serial # 5WS0295 Blows the 10 amp fuse to the key switch, red wire marked 105. The power relay that looks like a starter solenoid was hot, and the many yellow wires marked 308 have an abundance of connections. Some sections of 308 show various ohms between them and ground when testing for a short. Any help or anyone with access to an electrical schematic would be much appreciated. Thank you, Fred

    Don't push your luck here. I'm going after a new New Holland tractor early next week that kept doing near the same and the owner consistently replaced the blown fuse with a larger so he could finish harvest. Tractor will probably be salvage as the engine harness got a bit warm taking the hood, cab, dash, and all hydraulic hoses with it on the loader frame.

    Thank you Nige. And 1693TA, I know what you mean. I've seen a lot of bad things come from impatience.
