TEST PROCEDURE 2 – ARMATURE CIRCUIT OPEN
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 the posts from turning, disconnect wires from the A1 and A2 terminals
on the motor. Using a multimeter set to 200 ohms, place the red (+) probe on the A1 terminal and black
(–) probe on the A2 terminal. The multimeter should indicate continuity. If the reading is incorrect, a pos-
sible 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.

the motor. Using a multimeter set to 200 ohms, place the red (+) probe on the F1 terminal and the black
(–) probe on the F2 terminal. The multimeter should indicate continuity. If the reading is incorrect, a pos-
sible open field coil or bad connections at the terminals may be the cause. The motor will need to be
removed from the vehicle and repaired by a qualified technician.
