Took the boat out today and it started a little hard. Ran around for awhile and then floated for about 2 hours. Barely started, got over the ramp and it stopped running, got it started, barely, ran for a couple seconds then stop. Volt meter in boat said 12 volts. Got home and put hand held volt meter on the battery and it said 12.47 volts. Tried to start it, electric fuel pump ran for a couple seconds then stopped. Turned the key off they on fuel pump ran started the boat, barely started. Put the battery on the charger, needle went to 8 amps, back to 0 then 8 amps back to 0. After about 15 minutes of back and forth it now is taking a steady charge...Bad alternator or what? Thanks guys..
