Try this. Put one voltmeter lead on the NEG battery post (not the cable but the actual terminal) and the other on the starter case or mounting bolt, then attempt to crank the engine and read what the voltage is while trying to crank. Then do the same with the POS battery terminal the the battery cable connedtion at the starter (on the mounting bolt not the cable terminal end), crank and read the voltage. Voltage should be in the .200 - .350volt range and at most should be less than half a volt on both sides. You want the meter to be attached between the same two points as the POS cable and ground cable. This is a voltage drop test. It tests power and ground resistance to the starter while it's operating.
