Yeah my most interesting problem was actually 'after' an auto
electrician had had his hands on it, though I never got round to going
back round and giving them hell. I'd had a burnt out lighting wire
replaced, and then unrelated it the car stated cutting out at random
intervals, or when you accelerated hard, interesting reversing on the
starter motor as a 38 tonner approaches. After much f.cking about, I
ultimately I found out the sparky hadn't put the box back right, so it
was attached on the right side, but hanging lose on the left side, the
fuel pump feed comes out the top left of the box, so as the box rocked,
it was pushing up on the bulkhead and pulling the wire away from a
contact.
