5. If the measurement in step 2 is significantly low or high, disconnect the interconnect cable
from the J2 connector and repeat the measurement in step 4.
6. If the measurement in step 2 is still significantly low or high, replace the lower PCA. If
replacing the lower PCA does correct the problem, skip to step 9.
7. Remove the upper display panel and disconnect the interconnect cable from the upper
PCA. With the unit powered up, check the voltage between the outer two pins of the
interconnect cable for DC volts. It should read approximately 8.5 Vdc. If the voltage is
absent or significantly low, troubleshoot the interconnect cable and junction block per
Procedure 6.1.
8. If the voltage measurement in step 4 is correct, replace the upper PCA.I
9. If you have performed all of the previous tests and have not been able to locate the trouble,
call Precor customer support.
