Wow, that nylon shielded wire is very dear at $10/ft or more.

I used a similar thread cutting screw for the sides on that same machine, just found the photos. I dont remember if these were #10 or #8s, but I thought they blended better with a touch of paint on them.

Letterkenny reset in 2010.

You would think someone would put a set of eyes on that during the Reset... seeing as you dont know how many hours it was actually rubbing to get to that state.

Any recommendations on replacement wire?

I would go through the -24P and fine the OEM vendor and go with what the factory used, if available. Just with the addition of a rubber lined wire guide probably screwed into the bulkhead there to give permanent separation from the edge of the metal.

Same problem on mine. Original, with 500 hours. I caught it before the sparks flew, while inspecting the machine with the top off. I used fuel hose to sleve the wires, and wire ties to hold them together. The insulation was chafed about 1/2 way through on one of the wires.

Now you guys have me worried about my set...

Any gen set, should be checked as soon as you get it. Look at what is there, and consider what can happen in the future. It was SOP for us to use old, or new Inner tube, to wrap around wires, if we did not have time, and parts, to correct this problem. Anytime you see a wire, any wire, rubbing/touching metal, its should be addressed.

 

[Guyfang]

A fine example of correcting the problem. Not in the books. Not something required. But someone saw a problem and corrected it.

Finally getting around to teardown and wire replacement...

Looking at replacement terminals and wire now. Terminals are6 awg 1/2” and 1/4” ring nylon crimp. Wire is 6 awg milspec high temp M5086/2-6-9. Teminals are easy enough. Wire is nearly unobtanium and Very expensive.

Good find!

Go back to message #28. First two sentences. It rarly happens. Everyone is happy that the set works, and "assumes" it will for ever. Even reset generators are subject to this kind of failure. Because everyone "assumes" that if it was good up till now, its good till grandpa croaks.

Finished making replacement output wires A2/B2/C2. Added an insulated cable clamp and abrasion shielding as well.

There's nothing like getting to know our machines now is there? Good job, and I hope this fixes your problem!

Also applied Noico black insulation to one access door and the top panel over the main wiring.

Im glad everything is ok. Im trying so hard to learn generators but its been a struggle. Can i ask why is ypur bussbar not attached on the TB2 lugs? I know the tm says its detachable but is there a reason you took it off? Thanks, -a humble humvee mechanic
