Switch Kit Hookup Directions – LR 4.x OW Models

Permanent Connection

You can “hardwire” the motor for either of 2 modes:

MODE 1: Highest Top Speed

(This gives the greatest top speed. Depending on the topography where the vehicle will be operated, you may want to have your motor in a permanent high speed mode. This is suitable when the hills are mild and the vehicle does not have oversized tires or low gear ratio rear-ends).

Connection for MODE 1:

Make a small jumper wire and connect the LR stud on the motor to the S2 stud on the motor. A short battery lead is suitable for this type of connection.

MODE 2: Lower Top Speed – greatest Ultimate torque

(This gives slightly slower top speed, but improves the ability to climb hills or do other stressful activities where great speed is not a requirement.)

Connection for MODE 2:

Connect motor in car as usual. Leave LR terminal disconnected from the system. Connect nothing to the LR terminal!


Switchable Connection

If it is desirable to switch from the MODE 1 to MODE 2 on the fly, this can be accomplished through the use of an EXTRA forward/reverse switch common to most golf cars. EMP has instructions for the application of a Club Car Forward/Reverse switch and instructions for the connection. Both a mounting template and a Instruction sheet are included with these instruction.

This type of arrangement is convenient when the use of the vehicle varies widely. For instance, if normal use is 1 rider on flat ground, then the vehicle could be kept in the MODE 1 (high speed setting). However, if intermittent higher loading (multiple passengers, very hilly conditions) is encountered, switching to MODE 2 will protect motor and decrease the rate of battery drain.

Note: Should you decide to employ the “switchable” connection, any jumper leads supplied by EMP connected to the terminal studs should first be removed or the switch will not work properly.
