Cat 345BL blowing 10 amp key switch fuse

[FredMcAlister]

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.
