It appears there are a number of problems associated with this converter on the 'net, so here is mine. Maybe someone can help me with this problem. We rarely use an electrical site, almost always running our lights off the battery on the tongue. I charge this batter while towing, and also with a solar panel I duct tape onto the roof of my '01 Palomino Colt. All works well until the rare time I use shore power. When we do, the fridge and all 120V outletss work fine. But the lights and the gas sensor appear to run off the battery, and kill it in just a couple of days. We don't use the lights much, but I suppose it's enough to kill the battery, which is only 2 years old. Once the battery dies the alarm on the gas sensor goes off, and we need to scramble to pull the fuse to shut it off. From then on, no lights, which is a pain, and no sensor, which is a problem. The fan on the coverter runs, and the manual indicates it is supposed to charge the battery automatically. There is no switch on the converter. Has anyone else had this issue? I have no wiring diagram, and that seems to be a consistent complaint I've seen on this converter. The converter is OEM from the dealer/manufacturer. I don't want to go back to the dealer because we bought the unit out of town and it's a few hours drive. And the local dealer seems hesitant to get into the problem. If anyone has any insight into this I'd appreciate it. Perhaps it's a wiring problem, perhaps it's a converter problem, or perhaps I need to keep the solar panel on the battery and run the lights and sensor from that, and let the shore power handle the outlets and fridge? Thanks to anyone who can shed some (ahem) light, on this problem for us. NeverStop, NeverSitDown, Keep Moving!
