Computer Output Pins -

Hey John - The 4 static resistance tests I'd suggested is an ohm meter reading between the Pin 16 (Grd) and each of the pulsed Ground output Pins (14, 15, 32, 33) "On The Computer Itself" not on the connector cable side.

What you want to see from the circuitry inside the computer is a very high resistance (Meg Ohms ?) for each of these 4 readings. If the output power transistors are shorted internally - each of the 4 resistance readings will indicate a very low resistance value.
