13. Plug the line cord into the wall outlet and set the on/off switch in the “on” position.
14. Measure between terminals 1 and 8 of the data cable connector on the upper PCA with a
DC voltmeter. See Diagram 6.5 or Diagram 6.6. The reading should be approximately 8.3
Vdc.
15. If the reading in step 14 is good, replace the upper PCA. If the reading in step 14 is
significantly low, set the on/off switch in the “off” position. Disconnect the data cable from the
upper PCA.
16. Set the on/off switch in the “on” position.
17. Measure between terminals 1 and 8 of the data cable connector on the lower PCA with a DC
voltmeter. See Diagram 6.5 or Diagram 6.6. The reading should be approximately 8.3 Vdc. if
the measurement is good, replace the upper PCA. If the measurement is significantly low,
continue with step 18.
18. Disconnect the speed sensor cable from the lower PCA and repeat the measurement in
step 17. If the measurement is good, replace the speed sensor. If the measurement is
significantly low, replace the interconnect cable.
19. If you have performed all of the above tests and are unable to resolve the problem, contact
