Welding On Car With Computer. Burnt electronic components in weapons satellites transceivers and computer equipment. Ive got it saved if anybodys interested I can figure out how to post it.
Speculation runs rife regarding whether the negative terminal of a vehicles battery should be disconnected before welding on that vehicle. With that unpleasantness out of the way it is highly likely that the voltage current applied by the welding gear has damaged the low voltage control electronics responsible for operating the alternator. So its always possible to fry something but unlikley and the only way to be totally safe is to disonnect and remove the components which is not usually practical.
If the vehicle contains a high-voltage battery system check the service manual in order to shut down the hybrid system properly.

Both might pose dangers when welding on a vehicle not to the computer. Ford has a pretty interesting service bulletin about welding on F250s to F550s 2005 on.
