Re: Electrical problem after j-start
Reverse polarity isnt a good thing, anything with a coil works backwards and you blow the diodes in the alternator, I have seen newer cars than yours scrapped because of similar issues, the last one I reported on:
ECU - dead
Climate ECU - dead
SRS CU - failed to communicate
Dash pack - non operational - needle jammed on temperature and oil pressure
CD Player - dead - stinking
Body control unit - lighting - dead
Alternator - dead
Alarm - bemused
Immobiliser - locked out
The new list price of these parts made it a write off, although the insurance asessed it - they didnt pay out, it was just incompetence, the guy tried his home insurance too - nope.
So I hope you can ressurect the car.
