Using My Dad's ford laser (2001) to jump start my vehicle( semi flat battery) I made the mistake of attaching the jumper leads to the running vehicle first, not spotting that the positive and negative clamps at the other end were touching each other! Sparks occurred, and the Laser stopped running. Won't start. Has dash lights, but they fade when i try the ignition. There was a sixty Amp ignition fuse, but that didn't appear blown. One relay had scorch marks on its prongs(marked "circuit" from memory). Will it be a fuse/relay or will it be a blown ECU? Any suggestions? I was a bit surprised, as it wasn't exactly a reversed polarity(or was it?)

G Day Blake . Hey did the same thing once and what it did was killed the battery . If check your battery think will find it now has a dead cell so power will not hold in battery . Other thing is check the terminals give them a clean it may have caused bad earth at the posts on battery . Good luck .

Thanks guys. Chayton, points to you, as the massive short had caused the earth terminal to lose proper contact. I cleaned it off with emery paper, and adjusted the clamp slightly so as to get it to grip tighter, and hey presto, car runs, no damage. Thanks all.
