As it turned out, nothing went amiss. He had been making trays for ages and on all sorts of vehicles. The earth strap always was as close to the weld as possible and away from the front of the vehicle, also if possible.
So why the severe warnings by LR?
Are they just covering their legal butt?
Any military welders on here? How is it done on a ship, tank or aircraft with gazillions of electronics if you need to weld a beefy bit on some very expensive bit of military hardware?
cheers

If you place the earth right next to the weld you can generally get away with it. However just because your mate has never blown a computer or alternator doesn't mean it is the right procedure.

Thanks for the quick replies all.

I shall remove the earth from the battery, and place the earth lead for the stick welder as close as I can to where I am welding.

dont forget a heavy fibreglass blanket so the welding spatter doesnt ruin headlights/windscreen/paint
