Hi peeps,

I need to do some tig welding on the car (can't line it up ya see!) The battery obviously! but do I need to unplug any other electrics that are susseptable to 150amps going to earth ???

 

Many thanks

if its going to earth then there is no current path through any other components. only an induced voltage in the loom but cant see it. ive welded heaps of cars with fancy ecu's, curise control and never even disconnected the battery.

 

if your that worried though disconnect the loom from the ecu, but then where do you stop? auto box ecu, ascd unit? alternator.....

As a rule just disconnesting the battery is fine but if you do it by the letter u must disconnect the alternator ecu etc etc. but as above i have also welded many cars by just removing the ;) battery leads

1st time i removed a starter motor a year ago or so i forgot to remove the earth lead bang flash shitmeself LOL still here though yep removal of lead is fine remove battery completly incase the lead slips on the contact

ye well the battery goes directly to the starter and is un-fused so that would happen

just think, the CCA of a battery is up at about 220A and it doesnt do any damage when your starting the car in the morning does it?

Sweet, just making sure - cheers,
