Contour Enthusiasts Group Archives Forums General Troubleshooting Don't use your Contour to jumpstart another car...

I've jump started one of my other cars and expect to do so again this weekend, with no problems.

I haven't read jump start method in manual but presume you had the SVT engine on and that the last cable connection was to a ground away from battery. I presume also that you got other car started.

Sounds like your DRL relay (which has solid state internals) may have suffered a voltage spike and crapped out. There are also a couple of diodes in DRL circuit that might be sacrificed if you had reversed polarity.
But it could also just be coincidental.

p.s. PCM not involved in controllig DRLs.
p.p.s. I could give you more specific troubleshooting suggestions in later post, but you would require multimeter.
