    Dual pro charger help

    Went to unplug batteries this morning and have 2 flashing red LEDs, the 30 and 70%. Goes to this code immediately after an unplug & plugging back in . And does the same on my other batteries. Charger gone bad? Fuses are good on both legs.

    Maybe !! Have you tested the Voltage in each battery to see if they are fully charged ? Should be 13 volts when unplugged and 12.8 an hour later. Try switching the leads with the battery that did go green. Test each battery while on the charger, should bee 13+v. A meter is your best friend !!!

    Bank that has error seems to be putting out charge I guess. Voltage is higher when charger is plugged in
