RE: MIG welding and electronics

["Ian Lomax" <sfalfisto@domain.elided>]

i would recommend removing any components that have chips or circuit boards
in them, within reason.  ECU, trans controller (if an auto), spark computer,
climate control, etc.  better to be safe than sorry...

i'm not an EE, just an ME who pretends at times (but did used to work on
ECU's), so maybe someone else can explain why.

have fun,

Quick question from someone who is new to having electronics in his cars....

What precautions should be taken when MIG welding on cars that have EFI to
prevent the ECU being fried?

Presumably(?) remove battery leads - but is it also wise to unplug the ECU
from the wiring harness???

Anything else?

Thanks,
