Hey thanks for the quick reply guys!!!!
Pretty sure that it is indeed the ground cable. I hooked up a jumper cable from the - battery terminal to the back of the engine as a make shift ground cable (class A motorhome....engine inside
) and it fired up no problem!!!! Over and over without a problem.
So tomorrow I'll replace a few ground cables (frame to battery, frame to engine, and probably add a battery to engine for good measure)
Thanks again guys, you may have saved my vacation!
