Was the battery completely discharged when you did this and what type of car?

Not sure what the weak link would be. If you didn't try to start the car with polarity reversed I wouldn't think much would go wrong but look for wires that have been overheated. If you did try to start while reversed it might have baked the module on side of distrubutor and I'm sorry I don't know how to test the thing. If you have the battery up to full charge now and it cranks well with no spark I do think that would be the weak link. Sorry - that's just a guess,

Reverse polarity is a car killer. You may be lucky and only popped your main fuse (black 100 amp female fusible link fuse) check that. Will be in your cars instruction book. If thats ok, then you have a serious problem.
