Yup sleepy, that was the issue. Still had to find the calibration procedure for the new card though.

Found the calibration procedure in the MPE (A896) book. Apparently there's two types. Old and new style. The old style has the 3 pin jumper. The new style has the 4 position jumper and the single digit readout. I have the new style.

First, split the head., you have to see the tiller card to do this.

With the key off move the jumper from P (park) to T (train/calibrate). Turn it on and there should be a dash in the middle of the display. twist fully forks direction and press lift on the left side. the display changes. twist fully operator's direction and press the lower button on the left side. it changes again. Release the handle and move the jumper from T back to P. A dot should appear in the display to confirm the calibration is saved. Cycle the key and you're ready to go.

My card came set for an MPE. There's a setting for that too. The new card said "7" and the old one said "3" in the display. Key off, move jumper from P to C. Use the horn button to change the value. There's like 15 of them. Press the emergency rev to save it and the dot appears. It helps to take the belly button bumper (red button) off the head since it forces the horn down when the head is loose. Helps to leave it off and put it on AFTER the head is resembled.
