Just about to start welding my Disco 2. Apart from battery neg, should I disconnect anything else.?? ECU for example. I don’t want to fry anything :eek:
 
I've seen two cases when the BCU failed after welding but then the owners didnt disconnect the battery so maybe with battery disconnected it might not be a problem
 
Welding up a failed window-glass riser buggered my OEM alarm and remote door-locking on my Merc 500.
Got it replaced under warranty....... luckily.

Cheers SF. I usually just disconnect the negative, but never welded anything with as much electronics as a D2. Will have to just give it a go and cross my fingers. I might take the engine ECU out as an extra precaution.
 
Got one leg done today.

I’ll get the offside done tomorrow. Got rid of of the towing eyes. Bloody pointless.
 
Extensive welding done on both rear chassis legs. As said, disconnected battery negative lead only and removed the engine ecu. All back together now and everything's working fine. MOT next Friday, the 13th :eek:.
