Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
This may not be the root of your issue but with any of these intermittent voltage issues on these you should start with a loaded voltage drop of all battery cables. Put you volt meter between the positive post and positive connection at the under hood fuse block. Remove the even and odd coil fuses( this will also disable injectors) have an assistant crank the engine while you monitor the volts anything over .15v or 150 MV is too high and the cable needs to be replaced. Do the same from battery to starter and negative cable from battery to main ground.
i don't suppose you happen to know of any mechanics/car shops here in Hawaii (Oahu) that would have experience in this sorta thing do you? Cadillac dealership was little help.
Not off hand but my old service manager lived down there for a while I will call him tomorrow and see if he knows someone good
thanks so much!
No dice he said his friend he used retired. If you want to try and dig into it or have someone do it I can walk them though it pretty good.
Did you want me to show you how to test it?
