Applications without Seat Lift Feature
The wiring presented in Figures 4a and 4b is the same as in Figures 3a and
3b, except the components and wiring used to implement the seat lift feature
have been removed. This simpler configuration is applicable to vehicles such
as sweepers/scrubbers and scooters that do not have seat lift motors.
This installation includes a single-ended, 3-wire 5kΩ potentiometer
throttle, which is used with a reverse switch. With a wigwag throttle, a reverse
switch is not used and Pin 17 is left unconnected.
In this example, one set of B+/B- pins is left unused because the logic
circuit is wired directly to the vehicle's battery pack.
Note: When using the B+ pins (10, 11) an appropriately sized fuse must
be added to the circuit to avoid damage to the controller.
