GENERAL INFORMATION
The IQ System vehicle is equipped with a 48-volt DC, shunt-wound, reversible traction motor. The shunt-
wound motor is designed for use on the IQ System vehicle only. Club Car recommends that motors requiring
major repair be sent to a qualified motor repair shop; however, there are many relatively simple tasks that can
be performed by a technician with general knowledge and experience in electric motor repair.
MOTOR IDENTIFICATION
There are two types of motors used in 2005 model year IQ System electric vehicles: Model 5BC59JBS6365
(gray housing), and EJ4-4001 (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 Club Car dealer or distributor.
EXTERNAL MOTOR TESTING
Using a multimeter or continuity tester, the following tests can be performed without disassembling the motor.
NOTE: Tag the motor wires for identification before disconnecting.
TEST PROCEDURE 1 – INTERNAL SHORT CIRCUITS
See General Warnings, Section 1, Page 1-1.
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warnings, Section 1, Page 1-1.
2. Using two wrenches to prevent posts from turning, disconnect wires from terminals on motor.
3. Using a multimeter set to 200 ohms, place black (–) probe on motor housing. Scratch through paint to
ensure a good connection. Place red (+) probe on A1, A2, F1, and F2 terminals respectively
(Figure 15a-1, Page 15a-2)
. Multimeter should indicate no continuity. If readings are incorrect, motor will
need to be removed from the vehicle and repaired by a qualified technician.
See Motor Removal on
page 15a-3.
3.1. An incorrect reading from the A1 or A2 terminal indicates three possible problems: a grounded A1
or A2 terminal, a grounded wire in the brush area, or a grounded armature/commutator. An incor-
rect reading for the F1 or F2 terminal indicates a possible grounded F1 or F2 terminal or field coil.
