If I wanted to stop our engines from starting...I'd unplug the ICM connection. If you undo the plug wires..you'll still have that high voltage grounding somewhere.
I agree 100% that using the starter sounds less than safe and had to think about the consequences for awhile before deciding to proceed. With the socket engaged to the bolt, I turned the hb cw (by hand) until the handle was tucked into the motor mount so it wouldn't start flying on its own. After bumping the starter, I found the handle had not moved at all, was still tucked in the motor mount and engaged to the bolt which had now been backed out about 3/4". It worked so well (not to mention easy for a change) I felt it was worth passing on.
p.*. I did not have anyone holding the handle and it would be a very bad idea indeed.
