Bill, how old are the batteries? I would rather trust a volt meter reading than the lights saying 2/3 full. Start by checking the voltage on the battery posts with the engine running you should see about 14 volts. If not check the battery isolator/relay, it may be bad. If you don't see alternator voltage there check the starting battery. Your thinking may be right about your batteries but I would do these simple checks first then try to equalize them to see if they will come back. What kind off battery charger do you have and how many amps will it charge at?
