OK, Sat evening it was check batteries. The chassis one is about 24in long and 18in wide. It was less than a year old and ok as were both cables hooked to it. There are 3 more big 12 volt batteries hidden below that in a sliding tray. Here was a mess, cables carroded and 2 of the 3 batteries had failed to the point of leaking acid into the tray. What a mess. I removed the batteries and took baking soda to all of that mess in the tray. Used a stainless steal wire brush and cleaned all the cables and connections till they looked new. Last thing I did was paint the tray 2 coats of acid resistant paint. Early Sunday I headed to town, 25 miles, got 3 new batteries came home and installed everything back to the way its supposed to be. This morning they came and removed the alternator and I have yet to hear back from them. More later!
