Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I can help. Have you removed the battery terminals and cleaned them yet? I was working on a vehicle the other day that wouldn't start. I found corrosion between the terminals and posts.
Do you have a set of jumper cables?
You might have a bad ground. You can use the jumper cables to add an additional good ground to say the engine block or chassis.
Jumping the battery isn't going to help. You need to hook one end of the jumpers to battery negative and hook the other end to the engine block. You must find a good non painted surface on the engine to attach the cable to. Leave the positive leads not hooked up to anything. Try this and get back with me.
Have you tried to put power directly to the starter solenoid and see if it cranks?
