GENERAL INFORMATION
The IQ Plus vehicle is equipped with a 48-volt DC, shunt-wound, reversible traction motor. This 3.7 horsepower motor
is designed for use on IQ Plus vehicles 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.

TEST PROCEDURE 1 – Internal Short Circuits
See General Warning on page 1-1.
1.
Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles,
Section 1, Page 1-4.
2.
Disconnect wires from terminals on motor using two wrenches to prevent posts from turning.
3.
With 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. 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 27-2.
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 incorrect reading for
the F1 or F2 terminal indicates a possible grounded F1 or F2 terminal or field coil.
4.
Connect the batteries. See Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.
