A week ago today My battery that was unmounted down leaned over and the hot post rested on the motor, which ark it out the 2004 tundra V8 engine shut down after check what I thing are all the fuses I hooked battery back up and everything worked except the AC I have double and triple check all of the fuses and relay that I am aware of. I have just unhooked the blower mother and jump it from the battery and it almost jumps from my hands. I spoke with a tech from Toyota who suggested to me that their might be a problem with a fuse-able link beteem the battery and the starter. I have not yet to get enough confidence to take the thing that covers the start. However I would like to find a way to check to see if And Here is my Question "the compressor is dead. how must I do this?"
