Welding

[bigbobed]

I installed my fiver hitch today. Need to have the front ell brackets welded to the frame. Do I need to disconnect any thing electrical before the weld?

^...Personally, I'd disconnect both batteries. You're grounding to a source. Just my preference. Hope to see some pics of your new installation.

Please see the Allison transmission web site for additional info on welding. I noticed in the online owners manual for the 1000 that the TCM should be unplugged before welding. I don't recall the specifics, but that warning suggests to me that certain PROMs might be damaged if not unplugged.

Good luck.

Although anything can go wrong....

You are generally safe if you are using a welder that does not have high frequency start. That is what generally raises havock w/ electronics. A good wire feed w/o HF start will do the trick. To be safe, stick weld it w/ a lincold buzz box welder...

Good luck...
