WARNING
• See General Warnings on page 1-2.
GENERAL INFORMATION
The vehicle is equipped with a 48-volt DC, shunt-wound, reversible traction motor. The shunt-wound motor is designed
for use in Excel System vehicles. 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.
EXTERNAL MOTOR TESTING
The following tests can be performed without disassembling the motor using a multimeter or continuity tester.
NOTE: Observe the following before testing the motor:
• This is only testing continuity.
• Tag the motor wires for identification before disconnecting.
• Remove motor wire from one of the “A” terminals and one of the “F” terminals if testing while motor is
in vehicle.
• When disconnecting wires from motor terminals, use a second wrench on the lower nut of the terminal
post to hold post steady.
• Scrape a small amount of paint from motor housing (ground) and use this location when testing motor
terminals to electrical ground.
