98 Jeep Grand Cherokee - will not start - starter solenoid clicks once when engaged but starter will not turn engine - plenty of voltage (14V with jumper cables connected) going to solenoid - with screw driver jumpered terminals, solenoid to starter, but starter did nothing. I think the starter is bad.

This Jeep was not my vehicle. The owner had recently replaced the battery and the cable ends. The connections appeared to be securely fastened. But this was a bad assumption, as the positive cable end was not properly tightened to the cable. Consequently, the current flow to the starter was restricted, so there was not enough power to turn the starter. This was not discovered until after I installed the new starter, which would not turn over. The moral of the story is not to make any assumptions until you verify them to be true; and check the easiest fixes first. Fortunately, AutoTune accepted the return of the new starter and issued me a full refund. This Jeep was not my vehicle. The owner had recently replaced the battery and the cable ends.
