Will be having some welding done to the hitch receiver sometime next week and have started researching the welding checklist:
Welding Checklist (https://wiki.foreforums.com/doku.php?id=technical:chassis:welding)
I've already check the archives but not found any further directions/instructions. Does anyone know of old photos (or perhaps have photos that could be posted) to further identify any of these disconnect points?
Eg. What is location of breaker board for "C-2 - Transmission ground at breaker board"?
The plugs that are recommended to be disconnect under the item, "Allison ECU - Under dash / driver's side / both plugs" ... are those the two large RED plugs that are near the driver's feet?
Any further description or explanation of location (photo's) would be helpful.
Thanks for any and all input...
I believe that if you make a very good ground connection next to the welding area you do not need to do all the unplugging. I have seen that done at Xtreme by Rance Im sure. I may want to remove connections but cannot believe that all welders on trucks etc do this dissconnecting.

I believe I saw Wayne at Foretravel do the same thing. Good ground clamp next to welding.
You put your earth clamp on the piece your welding, That way, the current does not run through the vehicle your welding on,
I never disconnect any thing, On any thing Im welding,
If you put the earth clamp on one end of the vehicle and weld on the other end, It will fry every thing electrical, Wires will catch on fire or melt, Battery, Alternator, Etc, Stuffed, Not Good,
I do remove the positive and ground cables on both house and chassis battery(s), and place the ground clamp as close as possable to the work. I do that on the trucks we weld on at work as well, better safe than sorry.
Thanks everybody...
I had read the recommendation to keep the ground next to welding in the archives prior to posting, and I certainly will do that. I guess I was just looking for added insurance to try to make sure nothing gets fried.
By way of follow-up (and reference to another archive item), what I'm looking to repair is the hitch receiver. It's gotten wallowed out over time. My solution is going to be to weld some 3/8 inch plates over existing pin holes and drill to the standard 5/8 pin size - then use longer pin.
Thanks again.
Hey Bruce,
You are correct. Always, always disconnect at least the grounds on all batteries, current travels from negative to positive. For insurance disconnect both. It doesn't take long......No matter how close your ground is you will get some current 'leakage' that may effect sensative electronics.
