Re: welding and exaust Q\'s?
I have welded my plow frame many times,and forgot to dissconnect the battery first,and had no ill effects,but at another friends shop,I saw the tail lights of a F- 250 ford both light up like flashbulbs while he welded his rear bumper--after he was done,the truck had no tail lights,both bulbs were all black inside,and the altenator no longer charged--we changed the altenator,but it was a fuseible link that fried that caused the problem. I try to be very careful to make sure my ground cable is off the battery when welding--I would be especially anxious if I had a computer controlled rig with EFI,doesnt take much of a surge to wreck a computer.Considering how many vehicles get welded on at exhaust shops daily,its suprising there arent more problems--many of theese places dont even bother to dissconnect the battery(or know that they should,or just dont care!) /forums/images/graemlins/crazy.gif
