Mike,
If that is measured voltage with just the key on only, there are a couple of issues.
TB11-1 is a potentiometer circuit.
It should be ~4vdv with the foot off the accellerator smoothly sweeping to under 1vdc as the pedal is depressed.
Iirc, you can remove the wire from TB11-1 (#29) to verify the card output to the potentiometer. This is around 8vdc.
TB11-5 and TB11-6 should not be showing a bleed voltage on them simultaneously.
The voltages someone supplied to you for reference are basically correct.
I would still like you to measure the 6 TB11 screws with an operator in the seat asking it for very slow( creep) travel.
