Converter charger overcharging batteries
1995 sun voyager, my coach batteries got up to 17.2 volts on shore power when running the converter charger. Either my batteries have an internal short, or the on board charger is not switching into float charge. Is my diagnosis correct?
Update; After further investigation, the batteries are 12.6 with charger off and 13.2 when charger was on, so all good. The high voltage I encountered may have been due to a new LED motion porch light fixture I had recently installed. There must be a capacitor on the pcb that had stored a higher voltage when the charger is on. After turning off the charger, the high voltage drains back to battery voltage.
Thanks for your comments.
