This morning a friend's car battery was flat and they needed a jump.
I left them to set up the leads and got in my car and started it. Within 30 seconds, I smelt and saw smoke. The jump lead was on fire.
Immediately after getting out of the car I realised negative was going to positive, positive was going to negative. We must have had this set up for 30+ seconds
Turned the car off immediately.
Once everything had cooled down, I started my car with no problems. No visual damage to the ECU, and everything seems to be working. There are no engine warning lights.
I just drove home (100+ miles) and haven't experienced any problems.
I'm incredibly worried I've done untold amounts of damage, but I would have expected to see problems immediately if that was the case. (If the ECU had burnt out I would have at least expected a light on the dash, and the fuses seem to be ok as everything electrical I am able to check is working fine)
Have I just been incredibly lucky and got away with it? Or could I have done damage that isn't noticablen yet and will come to haunt me.
I'll be taking it for diagnostics asap but I've got to drive another 100 miles tomorrrrow before I am able to.
Please advise! I appreciate any advice anyone can give!
Many thanks
