Charging Batteries in Series
I have two 12-Volt deep [cycle] marine batteries in series and a 24-Volt charger that is supposed to taper down and stop when the batteries are fully charged. Q1: What happens if one battery is weak and takes a long time to charge or never gets to full-charge? Q2: Will the charger keep going and pos...

Re: Strange voltage reading
I ordered a new Minn Kota 12-Volt motor lifting assembly and installed it--worked like a charm. So the 48-Volts I had measured was just the peak of a 25-percent duty cycle: one cycle at 48-Volts and three cycles at 0-Volts equals an average of 12-Volts. The cycle rate has to be fast enough to not ha...

Re: Strange voltage reading
If the 48-Volts DC is being converted to 12-Volts DC by using a 0.25-duty-cycle, I would expect that in order for that conversion to work there has to be a load on the circuit. If there is no load, and you connect a DC voltmeter to the circuit, the voltmeter may read the peak voltage, 48-Volts. Tha...

Strange voltage reading
I'm replacing a 12-Volt DC tilt motor on a 48-Volt Minn Kota Edrive. In diagnosing a problem, I unplugged the two wires running into the motor and tested the voltage from the engine's circuit board into the motor, and saw 48-Volts on the DC setting of my multimeter. Not wanting to burn out a replace...
