>>>Yes, you're exactly right.   I have a starter from Pantera Performance 
Center, and their scheme had me taking the solenoid power from the starter 
end of that cable, with a short (2 inch) jumper wire.   Just as you said, when 
I would turn the key, power would flow down the main cable, reach the 
jumper wire, and activate the solenoid on the starter, but when I released the 
key, the starter would be very slow to disengage.

the tooth and might want replacing before long....

     If you read carefully what he wrote he said that he would be
     jumpering from the cable connection at the starter to the small
     terminal on the unit mounted solenoid leaving the firewall solenoid
     as from the factory. When this is done the cable between the
     firewall solenoid and the starter is dead until the solenoid is
     energized.

     > This then sends power to the starter and since the large cable is
     jumpered to it, it also energizes the starter mounted solenoid thus
     engaging the starter. This on the surface seems like a simple way to
     wire the starter. The problem is that because the starter is turning
     when you release the key the starter motor becomes a generator and
     feeds back to the solenoid keeping it energized for a few seconds
     until the start slows enough to drop out the solenoid. This was the
     method provided years ago by some of the vendors who could not
     explain why the starter would run on for a few seconds.
