14. Check the operation of the cycle as described in Section Four.
15. If the problem is still present re-connect the original upper interconnect cable and proceed
with step 9.
Troubleshooting the Lower Interconnect cable
16. Disconnect the lower interconnect cable from the lower PCA and the junction block.
17. Connect the by-pass cable to the junction block and the lower PCA.
18. Check the operation of the cycle as described in Section Four.
19. If the problem is still present, troubleshoot junction block
Troubleshooting the Junction Block
20. Remove the display housing per Procedure 7.13. Disconnect the upper interconnect cable
from the upper PCA.
21. Disconnect the lower interconnect cable from the junction block. Connect the lower
interconnect cable to the upper PCA.
22. Check the operation of the cycle as described in Section Four.
23. If you have performed all of the previous tests and have not been able to locate the trouble,

24. Both the upper and lower interconnect cable are easily disconnected at both ends.
Therefore, the simplest way to troubleshoot the interconnect cables is to by-pass them with
a known good interconnect cable. Remove the two bolts that fasten the display column to
the main bike frame. Carefully move the column away from the main bike frame. There are
two cables in the column, care must be taken to avoid damaging the cables as the column is
removed from the main bike frame. For conveniences, lay the column on the floor in front of
the bike.
25. Remove the left hand cover per Procedure 7.1.
Troubleshooting the upper interconnect cable
26. Remove the display housing per Procedure 7.13. Disconnect the upper interconnect cable
from the upper PCA.
27. Disconnect the upper interconnect cable from the junction block between the column and
the main frame.
