Had the volt meter go to zero for a while. Next time I started it it came up to 12.5 volts and eventually there was not enough juice to start the motor and had to jump it. I had been using two locators and ran the livewell constantly for three days. Charged the battery and it came up all the way. Any ideas why it only came up to 12.5 volts? TIA

Rectifier blown?

Start the engine and put volt meter leads on the battery terminals. Reading?

Rev to 2000 rpm. reading?

If the volts don't come up, you have a problem.
