Totally different scenario in that to what we're talking about - the solenoid has been removed for testing and a permanent +12v feed has been croc-clipped onto the exciter wire. The earth leac is being touched on the other solenoid terminal - in this case the pull-in terminal or the main output terminal of the heavy current switching part of the solenoid - i.e. the feed to the motor.

Perfectly normal test in an auto-electrical workshop - not so easy when the starter is still on the car and you're trying to diagnose the reason for sudden failure.
