I have a Minn Kota 330D onboard charger that is over charging my 2 12 volt trolling motor batteries. I checked them last night and both batteries had over 16 volts each. I checked them with everything disconnected from them. Does anyone know how much each of the charger leads should be readings.
Contact the factory for info.
Leave them disconnected from charger and everything else for 24 or so. Then check and see where they are. Sounds like one could have a shorted cell.
I disconnected them both last night and checked them this morning and they both individually are the same as they were last night. 16.8 and 16.9 volts.
I would have checked with Minn Kota, but they don't answer the phone on the weekends.

As mentioned, try a different meter.
measure a 1.5 volt battery with your meter
My problem was a faulty multi meter. ThanksQuote:
