14. Measure between TP20 and TP2 on the lower PCA with a DC voltmeter. See Diagram 6.5.
The reading should be approximately 7.5 Vdc. if the measurement is good, replace the
upper PCA. If the measurement is significantly low, continue with step 15.
15. Disconnect the speed sensor cable from the lower PCA and repeat the measurement in
step 15. If the measurement is good, replace the speed sensor. If the measurement is
significantly low, replace the data cable.
16. If you have performed all of the above tests and are unable to resolve the problem, contact
Precor customer support.
