GENERAL INFORMATION

The electric vehicle is equipped with a 48-volt DC, shunt-wound, reversible traction motor. The shunt-wound
motor is designed for use on IQ System vehicles only. It is recommended that motors requiring major repair
be sent to a qualified motor repair shop; however, there are many relatively simple tasks that can be per-
formed by a technician with general knowledge and experience in electric motor repair.

MOTOR IDENTIFICATION

There are two types of motors used in IQ System electric vehicles: 1) Model 5BC59JBS6390 (gray housing),
and 2) EJ4-4001 and EJ8-4001A (both with black housing). Do not attempt to service a motor that has not
been properly identified. If the motor cannot be properly identified, contact your local dealer or distributor.
Beginning with utility vehicle serial number 0924-028256, the CC P/N 102705001 IQ Electric Motor (Model
EJ4-4001) was replaced with CC P/N 103572501 IQ Electric Motor (Model EJ8-4001A). Concurrent with this
change is the elimination of the L-shaped mounting bracket and accompanying mounting hardware. The F1
and F2 terminal posts on the new motor have been changed from 5/16-18 thread to 1/4-20 tread. The new
motor is retrofittable to all prior model vehicles with IQ motors by using the CC P/N 103615001 Motor Terminal
Adapter Kit. The adapter kit consists of the appropriate nut and washers to fit the smaller F1 and F2 terminal
posts and includes installation instructions. Replacement parts for the new motor are the same as for the old
motor except for the brush plate assembly, motor cover plate, and frame and field assembly.

EXTERNAL MOTOR TESTING

The following tests can be performed without disassembling the motor using a multimeter or continuity tester.
NOTE: Tag the motor wires for identification before disconnecting.
Scrape a small amount of paint from motor housing (ground) and use this location when testing
motor terminals to electrical ground.
