To remove/replace a controller
NOTE: The control panel is serviced as one assem-
bly during the warranty period. Outside of
warranty, the individual controllers can be
replaced.
NOTE: The contactor assembly is not serviceable
and should not be opened. This would void
the warranty.
1. Disconnect the battery pack’s positive lead from the
contactor assembly:
1a. Remove the three screws that hold the left
access cover in place using a 1/2” wrench.
See Figure 5.25.
1b. Disconnect the battery pack’s positive lead
from the contactor assembly using a 7/16”
wrench.
See Figure 5.26.
2. Remove the left pod by following the procedures
described in Chapter 2: Body.
3. Disconnect the hall effect and communications con-
nectors from the controller to be removed.
See Figure 5.27.

taping up the cable lug with electri-
