Hi guys I am going to be doing some welding on my truck in the next couple of weeks and I was wondering if I needed to disconnect anythng so I dont fry it, possibly PCM. Just asking.

 

[Slated4Greatness]

Just make sure you ground it correctly.

It couldn't hurt to disconnect the PCM though..

 

[CSIPSD]

I never have with exhaust systems and such...

 

[TerminatorEngineering]

I usually just disconnect the battery terminals:shrug:.

 

[RSieck]

I've never unhooked anything, and never had a problem. Maybe we should send this into Mythbusters so they can solve this dilemma once and for all...

 

[kainers]

LOL I think that is a bad ass idea.

 

[genuineford]

Ok we never unhooked anything either when I worked in the exhaust shop but I didnt think it would hurt to ask. Thanks guys

Just to be on the safe side, I would disconnect the battery. It only takes a few minnutes to do it and if it was me I'd feel a-lot safer.

 

[Cat_Rebel]

Just unhook the batteries to be on the safe side.

 

[boggerr]

On old vehicles I never had a problem but with all the computer crap now a days I disconnect the batteries

 

[genuineford]

Ok will do just to be safe

I didn't do anything but grab a fire extinguisher as far as safety when I welded the entire frame back together after sectioning ~15 inches for the shortbed

Still runs good

Couldn't hurt to unhook the batts though.

As stated unhook the bat. I have welded on many of a rig and always un hooked the bat. if it has a comp. in it. Why take the chance? For the time it takes well worth it.

You should unhook the batteries. The ecm doens't like power spikes. You also should weld on the frame as it's heat treated if you can avoid it.

 

[Charles]

Now that I think about it, that truck has a battery disconnect switch in the front grille that was in the "OFF" position.

So then yes, my batts were actually disconnected.

I am going to start building my pipe bumper so I wont be welding on the frame. I had the bumper off today doing some mock up. I will get some pictures up when I get something accomplished.

 

[DarkShadowDiesel]

that sounds awesome, def put up some pics, i always wanted to do that.

This is what the main part of the bumper is going to be made out of. I got templates for the brackets I am going to make. I still need to get some more material then comes the fun part.

 

[Dysfunctional]

I have welded on my rockcrawler probably hundreds of times without ever undoing batts or worrying about the computer. Still runs great... rolls over alot...hmmm maybe that's the problem :brightidea: :flipa:

Are you sure that bumper will be stout enough?
