Jump across the two big bolts on the starter. If it turns over, it's in the elect. system. If it doesn't turn over, use battery cable from battery + to big bolt on starter (try each one separately. If it doesn't turn over, its the battery, the starter, or your not grounded. If it turns over, the big wire from the battery to the starter is bad.
There aren't the typical 2 bolts on the starter, just 1, which is the positive lug. No negative wires to the starter at all. As near as I can tell, the ground is through the block. The large positive wire runs to the lug on the solenoid part of the starter and is hot at all times. I believe that the smaller (12 gauge?) wire that clips to the solenoid is probably the trigger from the ignition. I'll be testing this after work this evening.
