Here is what I tested today:

I ran a jumper cable from the positive battery post to the positive post on the solenoid and attempted to start - Failed

I removed the trigger cable and touched the trigger blade on the solenoid with the jumper cable running from the positive post on the battery - Failed - This may be the issue. Shouldn't the solenoid have been triggered and in turn triggered the starter motor?

The problem is intermittent so it is possible that when I took the starter in for testing it passed.

I tried it again with the ground cable to the body of the starter to ensure I have a good ground and the positive cable directly prom the battery to the trigger. - Failed

I'll remove the starter again and see if it still fails.
