My '08 Tracker Marine Tahoe Q7i has been sitting for about three months of no use and last week I charged up the battery and tried to start it and the ignition switch does not make a sound. It doesn't turn on any of the accessories or crank the motor. I replaced the ignition switch and the main fuse with resettable button from the battery lead but still nothing. Not even a click. All leads have been tested for continuity and voltage and everything seems to be okay. Is there another fuse someplace that I'm missing? I also traced all wires that I can see and feel but still nothing. Thanks in advance for your help.
