How do I get the Minnkota /Promariner to charge again?
This guide will help get your Minnkota 315D/330D/330E and Promariner to charge your unit again.
It sounds like the unit got left on or has not been charged in a while. If the charger is showing check connection it means that the battery has dropped below 6 volts and the charger is in a self-protection mode. The way to clear it is to hook up a regular 12 volt charger and charge the battery that is showing the check connection fault for 2-3 hours (you will not need to unhook any wires just make sure the unit is off and the Minnkota/Promariner is unplugged). After it is charged unhook the 12 volt charger and plug the Minnkota/Promariner back in and it will charge it up the rest of the way. I have attached a link to a video to show how it is done. https://youtu.be/r28Vxc91zFA Have a great day.
