receive a heart rate reading within ten seconds.
4. If a hand held signal is not being accepted, access the diagnostic program (Procedure 2.1).
Advance to the heart rate display portion of the diagnostic program. Verify that a hand held
signal is not being accepted by firmly grasping both the right and left hand held contacts with
the opposite hands, right hand on the left handlebar contacts and left hand on the right
handlebar contacts. Cover as much of the contact surface area with your hands as possible,
you should receive a heart rate reading within ten seconds. If a hand held signal is still not
being accepted, skip to step 9.
5. If a hand held signal was accepted in step 7, the hand held contact wiring is reversed. The
end of the wire harness that connects to the hand held contacts in the handlebar is
segregated into two groups. One group has blue shrink wrap around it and the other group
has black shrink wrap around it. The "blue" group must go to the right hand contacts and the
"black" group must go to the left hand contacts. In both groups the black wire must go to the
lower contact and the red wire must go to the upper contact. If necessary, rewire the hand
held contacts as described above and test as described in step 6.
6. Refer to Diagram 6.5 for the following measurements. With an ohmmeter measure between
pin 4 of the input connector and the lower right hand held heart rate contact on the
handlebar. The reading should be 1 Ω or less. Measure between pin 3 of the input
connector and the upper right hand held heart rate contact on the handlebar. The reading
should be 1 Ω or less. Measure between pin 2 of the input connector and the upper left hand
held heart rate contact on the handlebar. The reading should be 1 Ω or less. Measure
between pin 1 of the input connector and the lower left hand held heart rate contact on the
handlebar. The reading should be 1 Ω or less. If any of the above readings are greater than
1 Ω, replace the heart rate PCA to handlebar wire harness.
No hand held reading - No chest strap reading
7. Access the diagnostic program (Procedure 2.1). Advance to the heart rate display portion of
the diagnostic program. Verify that neither a chest strap signal or a hand held signal is being
accepted with either a heart rate test transmitter or a chest strap transmitter.
8. Check the plug/connector connections on both the heart rate PCA output connector, and
upper PCA (J1).
9. If neither a chest strap signal or a hand held signal is being accepted, measure between pin
1 and pin 2 of the output connector for 5 Vdc. If 5 Vdc is present, replace the heart rate PCA.
