I have had to replace the battery on my 1988 FLHTC every year for the past 5 years.

The Stator is kicking out AC volts, the regulator/rectifier is charging @14.5 volts at the battery.

The batteries are just dying, putting a snap on battery tester on each one tells me the battery is no good and to replace it.

I have tried genuine HD batteries, YUASA lead acid, and most recently a MOTOBAT AGM, all have failed.

I have used OPTIMATE and an AGM specific optimizer. once removed from the charger and a volt meter put across the terminals the voltage drops like a countdown clock.

Can anybody give me a clue as to what the hell is happening?
