No charging when plugged in to shore.

185 RB SLX 2012. Have used 4 times. In April everything was working. I would run small genset to recharge the night before battery use. Went out this past week and batteries were dead. 2.2 volts. put charger on for truck and batteries went up to 100 % but I don't believe it. Put VOM on battery got 12.0 volts, with shore power off. With on, 11.99. Now what? checked all fuses and even replaced each and every one. still no charging the batteries. What would you all recommend? Thank you in advance.

Perhaps you have a bad cell in the battery? If you leave a battery dead for too long a period it will not come back or hold a charge. Best to pull it and have an auto supply put a load on it after a 12Hr charge to test it. That's where I would start and work backwards from there towards the converter.

Connections clean? Clean them and spray with a battery sealer if there is any corrosion.

It sounds like your batteries have been discharged to the point of no return. If you are not hooked up to a power supply when not in use, you need to put a disconnect into your battery system. There is enough parasitic drain on your battery to kill it in a week or two. If you have only been charging it with a genny the night before you intend on using it, chances are your battery has never had a full charge!! Your batteries are not charged until you are at least 12.7 volts. 12.2 is a battery at 50% power. You are well below that meaning that you probably need to replace your battery and come up with a disconnect or keep it plugged in to shore power. Charging with a generator will work if you take away all parasitic loss and and run your generator long enough to bring your new battery up to 14.4 volts. Repeated deep discharges will destroy any battery prematurely.

Thankyou for the replys. Turns out the converter was shot and a new one is being shipped to me. No warrantee, too old. I have installed a battery switch for battery one and battery 2 and ALL, and OFF.
