Car Batteries
Ford Probe

Why is the battery gauge on the instrument panel of a 1996 Ford Probe reading HIGH whether the car is idling or in motion?

Two options. Either the alternator is bad (voltage reg), or the computer is no good. Turn the head lights on (at night). If thy flicker, like high beams, then the computer is fried. C.E.

Yes, it can ruin the battery by overcharging it. If you are reading between 13.5 to 15.5 volts at the battery with the engine idling then more than likely the alternator is good and you battery has a dead cell. A fully charged battery will read 12.6 volts with the engine not running.

unstable idling and battery indicator lights on.

Cleaning the battery terminals had nothing to do with the engine not idling properly. Just a coincidence.

Yes, as long as the charging system is is good working order.
