I see a black battery cable to my house battery and a much thinner black wire (maybe 10 gauge?) with a ring connector, but I can't find the positive cable. It's possible I took it out a couple years ago because it was old. Does anyone know where the positive house battery cable originates from, please? Thanks

I'm currently dry camping on the west coast of Mexico. I don't have solar but have been using a generator for a couple hours daily to charge up the single deep cycle house battery. This worked fine for many months, here and elsewhere, combined with a few hours of charging off the alternator while driving once a week or so. Now, however, it seems the battery charging aspect of the power converter, an old B-W 6325, has ceased working. This appears to be the case because while the generator is running, the power to the 12v circuits in the coach is at around 13.2v but the power at the lug connected to the house battery remains at whatever voltage to battery was at before firing up the generator. Correct me if I am misdiagnosing this or testing incorrectly. I'll install a replacement converter when we get back up north, but in the meantime I'm nowhere near anywhere for another month or two. My question for someone who knows more in this area than me: since the converter is putting out 13.2v to the house circuits, for lights, pump, etc, would it be possible to put a jump wire in from one of these house circuits on the DC fuse board to the house battery lug? I could easily disconnect the lead that is going to this lug from the converter, just to prevent any weird loops or feedback, but is there some other aspect of the power to the house circuits which might damage the house battery? Perhaps too much amperage? (I don't have an amp meter with me so no way to test what that is.) The only other solution I can think of is running the engine, which works fine to charge to house battery but burns a lot of fuel. Thanks in advance for any assistance or suggestions.

Where is the best location to put 3 to 4 house batteries (possibly sealed 12 volt Group 29's) if you were starting new with the gutted interior of a 1982 18' Toyota Sunrader? Forget the area behind the drivers seat because thats where I built the new bathroom. I can put one battery under the hood but what about the other 2 to 3 batteries? I'm thinking weight distribution here...if it matters. Thanks P.S. I just asked this same question at the Toyota motorhome Yahoo group too.

Walmart sells the EverStart Maxx Group Size 29 Marine batteries for $100. These are 12 volt batteries with an amp hour rating of 114. Apparently they are made by Johnson Controls and come with a two year replacement warranty from Walmart. Do you think 2 or 3 of these would be good for house batteries with solar panels? Here is the link to it at Walmart: http://tinyurl.com/bb2utzu Thank you
