What causes a 1989 Chevrolet Celebrity 6-cylinder to only click and not start after you replaced the alternator and the battery is fully charged?

Answer 1

This sounds like a ground problem. In the electrical field you can have all the new parts it takes to make a car go but if there is the sligthest hint of a wire not being grounded good you can get clicks or nothing at all. Grounds are found in order of what to check first: 1) The battery + & - while the battery is new the connections must be cleaned and sufaces cleaned with a wire bush, or by pooring Coke Cola on the terminals. 2) I found another ground on the right side\passager side up by the right head light. It has a plastic cap cover it and located to the right of 3 fuses. If step one doesn't do it, clean the connections at this area. 3) If steps 1 & 2 result in the same look for a ground strap coming off the starter located under the car close to the fly wheel & transmission. If there is a ground strap disconnect you battery cable so sparks don't fly and reduce the risk of a light shock, then remove the bolts that hold it on, clean with wire bush the bolt, ends of the strap, and connects to the starter and frame the strap goes in. Not for sure this car has such a strap but I had a 74' Cad that was dead for 3 days while I replaced every electrical part I could think of until the service manager from the Cad dealer told me there was such a thing. I cleanned it and it started right up. Hope some and any of this helps. Have the starter checked at a parts store for a bad solenoid. Make sure wire connections are clean. As well as all grounds. Oil leaking onto any of them can disrupt the connection.
