When the negitive is connected to the battery the truck tries to crank with no key in the ignition. What do I need to look at ?
Battery sparks and tries to crank the truck when the negative cable is attached. No key is in the ignition, the truck cranks but doesn't turn over. Starter is 6 months old, it has a new starter solenoid , voltage regulator and ignition switch. Where else do I need to look ?
