I didn't realize these things went bad and would always be there to charge up batteries, UNTIL...... dead battery 45min into a fishing day. I was stunned! Put the voltmeter to the battery, then came home and put the voltmeter to the charger. Uggh. Time for a new Minnkota 320.
Well, now I have my newest boat at 8yrs. I wonder when this one will be ready to zero out???
aren't there fuses involved with chargers? I'd look into whether it's truly "shot"
