QUESTION:
My 1999 Mercury Mountaineer has plenty of battery power, but will not turn over - any ideas? Attempted to jump start battery - but that was not the issue. The battery is fine. It simply won't turn over, I can hear a metallic click, but the starter does not engage.
ANSWER:
If you idea of plenty of battery power is the fact that the lights and radio work then it can still be the battery. The starter requires around 250 amps where the radio only requires around 5 amps. 99% of all no starts are caused by a failed battery. You can have the battery load tested or use a battery out of another vehicle to test.
Once you have ruled out the battery, the next step is to test for power at the "s" terminal (small wire) at the starter while someone holds the key in the "Start" position. If you see battery power , then you need to replace the starter.
