have the theft warning car may not restart since altenator has been changed tried to reset alarm according to cadillac owners manual still wont work car only starts sometimes others its click click click. PLEASE HELP

 

if it comes and goes, it sounds like you have a wiring or security unit problem...

 

For anyone reading patrick the tech support was right....the problem is in the voltage the cable going from the battery to the starter needs to be replaced. The cadillac dealer in demotte Indiana looked at it yesterday for no charge. See there still are some good honest people left in this world
