Before you change out the starter or it's solenoid, have someone load test the battery. The "clicking" sound is too often mistaken for a faulty solenoid when all along it was a battery getting weak.

It will only cost a couple of bucks if that. A lot of places will load test for free.

By the way, some people here are big advocates of what's known as an "open circuit voltage" test. They assume that because a reading of 12.60 or better is returned that the battery is OK.

Wrong.

The only legitimate test in this case is a load test.
