Re: testing Solenoid
You do not have a short. Shorts blow fuses. You very likely have a bad solenoid. Any testing requires a known good, and fully charged battery. Assuming it's charged is not acceptable. Use a short piece of wire (14 gauge or larger) that is bare on each end. Touch one end to the post that has the POS battery cable on it and the other end to the small post with the wire from the ignition switch. This essentially replaces the entire ignition switch circuit. If the starter spins you have a switch/wiring problem. If not, use jumper cables to test the starter. Connect one end of a jumper cable to the POS terminal of the battery and the other to the large post on the starter, or the large post on the solenoid that has the starter cable attached. Connect the negative jumper cable to the negative post on the starter and the engine block. If the starter spins it is ok and you now have shown the solenoid is bad.
