9. With throttle pedal fully depressed, measure the following:
CIRCUIT ACC CARD
TZ6661
510(+)
to EB2635
952(-)
EC1806
10. Release throttle pedal.
11. Measure voltage at circuit 525 and 952 while slowly pressing throttle pedal from minimum to full
throttle.
For adjustable pedal with TZ6661/EB2635 card, meter reading should start from approx-
imately 0.70 vdc and increase to approx. 4.35 vdc in a smooth and linear fashion.
mately 0.54 vdc and increase to approximately 4.30 vdc in a smooth and linear fashion.
If there are positions of voltage drop off, replace pedal potentiometer.
12. Release throttle pedal. Measure circuits 73R to 710 with pedal released.
Measure 0.0 vdc.
13. Depress throttle pedal fully. Measure circuits 73R to 710 with pedal pressed fully.
Measure approximately 26.0 vdc.
14. Release pedal. If step 12 or 13 readings are incorrect, replace accelerator card.

be performed in conjunction with accelerator pedal setup on trucks equipped with the "Fuel Saver"
circuitry.
•
Turn Key Switch and Control Power On.
