6. Repeat the measurement in step 5 at terminals 1 and 2 of J8 on the lower PCA. If the

voltage is missing or significantly low, replace the speed sensor assembly.

7. If you have performed all of the above tests and the stride rate is not displayed when the unit

is operated, there are three parts that could cause the problem. There are not any good

tests to check these parts other than substituting a known good part. They are lower PCA,

ribbon cable and upper PCA. Replace only one part at a time. If the new part does not

correct the problem, replace the original part.

8. If you have performed all of the above tests and the speed sensor is still not functioning, call

Precor Technical Support.
