On cars, clamping next to the weld is risky, but usually done. Muffler
shops routinely mig without blowing up the ECM this way, and on late
model cars, even disconnecting the battery can lead to a world of hurt,
as many systems need to be re-coded or initialized. If it were MY car,
I'd disconnect both battery terminals, connect them together with a
jumper, and unplug all the modules before welding. The latter might
require considerable labor time for access to them.

I need to reinforce a guard on the mower deck of my zero turn mower
(Grasshopper 52" w Kohler Command engine). I'll probably take the
battery out just because I have to tip it up at a 45º or steeper angle
to get to the underside easier and I don't want to take a chance of
the battery leaking. I'll probably clamp the ground on the deck not
far from where I'll be stick welding. Do I need to do anything
special to keep from frying any electronics on the mower?

If I were welding on a car, what do you do to prevent ruining
electronic devices?
