http://www.contour.org/ubbthreads/showflat.php?Cat=&Board=trouble&Number=243345&page=0&view=collapsed&sb=5&o=7&fpart=1 There are wires under the battery that can get bare and create a short from +12 to ground. They run between the pos battery terminal and the fuse box next to the battery. These can become corroded with battery acid and if they touch ground, watch out.
