To day I was installing my two 6 volt batteries in my Grand Canyon in preparation for my Texas trip in a couple of weeks. I had the batteries out as they did not seem to be charging properly. What I had found was corrosion and rust build up on the positive terminals. It seems when I had the batteries out last the wing nuts had loosened on the positive terminals. This had caused corrosion stopping the batteries from charging. I have now done away with the wing nuts and now use a regular nut that can be tightened with a wrench. I also used two flat washers and a lock washer. All of this hardware including the nut is stainless with hopes that it will not corrode. I think when I slid the batteries in the wing nuts loosened a little as the positive wire is very stiff. Before I put the batteries in I hooked up the trailer to the truck to check the voltage from truck to trailer. I found that I had 12 volts coming through to the battery, turning off the cut off switch no voltage coming through. Now I unplugged the truck and plugged into shore power and 13.5 volts from the converter. Again I turned off the battery power switch and no power to the battery. I had always wondered if the batteries still charged when that switch was turned off now I know.
