It is possible they are too low for the charger to read them and turn itself on. Try jumping a known good battery to the discharged battery and see if it turns the charger on. You can also take bank one off its current battery and put bank 2 on that battery and see if bank 2 lights up, do the same for bank 3. You may have a charger issue, but with that battery voltage it indicates a battery issue.JohnI concur completely . — ” How did the batteries get that low ? ” — would be my question ……. Something I found out on my M / K 101 , if you dont turn the switch on the pedal to ” OFF ” when not in use it keeps the speed control energized , which draws voltage ( albeit a small amount ) all the time . — This could draw them way down if stored for an extended period of time without charging — Id definitely check the batteries first , before you condemn the charger . — I speak from $325.00 dollars worth of experience . — Now I have an extra charger that works just fine . — Hoss As an FYI, the control board, if it is the newer type with the magnetic reed switch under the actuator button, will continue to draw power even with the mom/off/con switch on off. On any digital motor (some Motorguides have an on/off switch on the side of the footpedal), the power needs to be disconnected from the trollingmotor for both charging and safety reasons when not being used. As stated above, they (digital trollingmotors) will draw current as long as connected to a battery.JohnJones Trolling Motor Services870 773 3474Motorguide/MinnKota/PowerPole/Lowrance/Humminbird
