Major Mouse Wiring Harness DamageTC35D

Thanks to all who offered some help. I am glad to say the tractor is running again! I did not end up having to pull wires out of connectors, since there was just enough to get a strip and new butt connector on. I did end up not using the 8 gang connector that was OEM. I just zip tied the bundle together and put individual quick connects on that circuit.

Thanks for keeping us up to date. Too many posters never let us know they found a solution.

I have a NH TC35D with under 300 hours. Over the years it has not been uncommon to get on the tractor and find that a mouse has lunched on a wire or two. I would trace it down and splice in a piece. This time it's different. There was a major party on my wiring harness and it is SHREDDED. I can't believe the amount of damage. A replacement harness is around $800 and that is just for 1. And just splicing in a section of red wire isn't going to do the trick this time, either. I have gone so far as to order a kit of colored wire to color match the damaged wire. New Holland does a decent job of labeling the wires, so I should be able to identify both ends of the same wire at some point.

The biggest issue is that a number of wires are chewed right down to the termination point. The relay or gang connector is there with a small nub of wire exposed. On most I can identify the color of the wire, but that is all. I am no expert at reading wiring schematics. Most of these parts no longer have the P/N visible on them, but they may have 2 or 3 of the wires identifiable. How do I identify the parts that these are, and how do I connect to them once I do? Is it possible to remove a single wire from a gang type connector and replace it?

Thanks

Count two of these.. My TC35D has the back of the relay block eaten down to a few bare nubs of wire. Mice usually go for the insulation. For some reason they ate wire ans all. What did you finally do?

Using the wiring diagram in the owner's manual, I went g=thru wire by wire and spliced them back together. I started with the ones I could identify 2 ends, and thru elimination, identified the rest. I used actual color and gage for replacement and carefully labeled each wire. the machine is running again, and I just pulled a dead mouse out of the wiring harness. I hope it's not round 2!

Good luck!!
