I recently purchased a bass boat, everything worked fine when test drove, but the first day I took it out on the water the TM didn't work. After testing the batteries with a voltmeter all the batteries were fine except one that read as negative 11.9. I have a mini kotA I-pilot and there is still some power coming to it as when I click the test battery button on the motor it will light up but it will not turn on or sync to the remote. I am new to boats and deep cycle batteries does anyone have some advice?
