THE TESTER SHOULD NOT
LIGHT (MULTIMETER SHOULD
SHOW NO CONTINUITY)
1.1. An incorrect reading from 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. If the S1 or
S2 reading is incorrect, it indicates a possible grounded S1 or S2 terminal or a grounded field coil.
TEST PROCEDURE 2 - ARMATURE CIRCUIT OPEN
1. Disconnect the wire from the A1 terminal and the wire from the A2 terminal on the motor. Using a mul-
timeter set on ohms (Ω), place the red (+) probe on the A1 terminal and the black (-) probe on the A2
terminal (Figure 24-1). The reading should be continuity. If the reading is incorrect, a possible open or
poor contact in a brush assembly and/or open armature windings may be the cause. The motor will
need to be removed from the vehicle and repaired by a qualified technician (See Motor Removal,
Page 24-3).
TEST PROCEDURE 3 - FIELD CIRCUIT OPEN
1. Disconnect the wire from the S1 terminal and the wire from the S2 terminal on the motor. Using a mul-
timeter set on ohms (Ω), place the red (+) probe on the S1 terminal and the black (-) probe on the F2
terminal (Figure 24-1). The reading should be continuity. If the reading is incorrect, a possible open
field coil or bad connections at terminals maybe the cause. The motor will need to be removed from the
vehicle and repaired by a qualified technician (See Motor Removal, Page 24-3).
