Has anyone run into problems or adverse effects doing this ? I pulled the ALL fuses, Disconnected the PCM plug before welding and now I have 1/2 of my dash lights - Bulbs are good.

I welded the EGR header bung nipple and also tacked the Y header flange before clamping (slip- fit , NO donuts).

Just wondering if I screwed up my electrical when I welded or it's just a coincidence ?

 

I've heard of this happening, but not loosing half ur dash lights... strange.

 

Yea , I don't know how it could of surged past either of the fuse blocks, unless it used the back door and found a ground (engine strap/cab to frame rail). Idunno, I'm pulling the cluster again - Checking for cracks in the PSB this time - It's cracked before (factory defect)

 

Well, just gotter back together, couldn't find a damn thing wrong with the cluster panel/board..I don't know what I did, but it works now - everythings lit up. I guess I should of tried kicking it first :o

 

A good kick usually does the truck, I remember this old TV we had
