Well I took the starter out last night and it's definitely not responding to voltage at all. I think I'm going to try one of Karl's adapters and a gear reduction starter along with a new cable to the battery. My current cable is slightly frayed at the battery end and at least 2 strands of wire are broken. So hopefully that's a safe bet. I will probably try the voltage test you described after new starter but before new cable. Seems reasonable.
