when I was working on changing the headgasket, I accidently knocked the dist off a shelf and it broke the rotor off. i got a new one on it but is there anything that could have been damaged? everything looks ok, but under the rotor there are two spots where wire is coiled up and was covered in either glue of a little plastic cap well one of them come off and wire is exposed but none cut, could that hurt it? any way of testing it? that still doesn't solve the engine light not coming on because I am sure it is in the right place.
