Welding vs. computers (was RE: [Gmecm] Wide band 02 sensors)

[Doug Chase]

Could you elaborate on how this happened?

I've heard stories like this but never any details.  I've heard things like
"disconnect the battery before welding on a car or you'll fry the computer"
but that doesn't make sense to me.  It seems that if you choose your ground
carefully (as close to the weld as you can get it, both physically and
electrically) there should be no problem.  I've welded on a lot of cars like
this and have never damaged any electronics.

I'm interested in hearing more about how this happened to you guys so I can
avoid it.

Could also be that someone welded on the dyno frame while the wideband was
on it.  We had a problem like that with someone welding on the steel rear
frame.  It was still bolted to the front carbon tub with a PI data
acquisition system in it... fried the PI, worth about 5k used.
