Never had any probs whatsoever with my car starting before......never left the lights on before either.......Tried to get a jumpstart off a Ford diesel pickup (2 batteries)....no go....Hooked up a battery charger and left in on for 15 minutes...voila!! It started right up....my point......I figure the diesel draws too many amps for the jumper cables to handle????? Are there special cables for diesels????
