Another interesting aside - the battery was put in by Advance in 2006! It tested for more cranking amps than it actually is listed for and the alternator is perfec t. When we tried running codes, the machine couldn't even begin. I checked the fuses again, but could it be a bad fuse, relay or coomputer?
Try removing & cleaning the battery`s ground wire, especially where it bolts to the chassis, clean it, and reconnect to make sure of a solid ground connection. Even though that battery *tested* OK, at 6 years old, it would shoot right to the top of my "Prime Suspects" list. Can you swap in (temporarily) another battery that is known to be good just for the process of elimination ?
