[T3] Car Won't Start

[Keith Park]

In the rust belt, that little braid wire between the solenoid and the
starter can rot away and cause this kind of intermittant.

Shorting between the 2 large studs on the solenoid should produce 
exactly that result.

If you short between the upper stud and one of the push-on 
connectors, you should get normal starter operation. There may be 2 
different push-on connectors there, but only one of those will give 
this correct result.

In a later message, I believe you say that you did this and got a 
sort of "air hammer" outcome. This points to a bad connection 
somewhere. What's happening is that the solenoid pulls in with a bang 
and then the starter starts to draw a lot of current. The current 
causes a large voltage drop across the bad connection so the voltage 
available to the solenoid is no longer sufficient, so the solenoid 
drops out. This ends the current and the cycle repeats.
