EXTERNAL MOTOR TESTING
Read DANGER and WARNING on page 15-1.
Using a multimeter or continuity tester the following tests can be performed without disassembling the motor.
Test Procedure 1 - Internal Short Circuit
1. Place Tow/Run switch in the TOW position and disconnect the batteries (Figure 15-1, Page 15-2).
2. Using two wrenches to prevent posts from turning, disconnect wires from terminals on motor.
3. Using a multimeter set to 200 ohms (¾), 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 15-1, Page
15-2) . 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, Page 15-3 .
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 incorrect reading
for the F1 or F2 terminal indicates a possible grounded F1 or F2 terminal or field coil.
