thanks larry. i just changed a new batt, and the "engine off" reading is fine at abt 12.4.

BUT with the engine at idle, the voltage drops to about 12.1! And on revving, it goes up to about 13.1.

can i conclude that the alternator is on its way out? has it anything to do with the voltage regulator?
