Step 2. Inspect fuses (1,2, and 3) on voltage reducer (4) and fuse (5) by removing cap (6) and fuse (5) from
receptacle (7).
If fuses are bad, replace fuses.
If fuses are OK, go to step 3.
Step 3. Check distance between proximity sensor and gear.
If distance is not 0.020 to 0.022 in. (0.508 - 0.559 mm), adjust proximity sensor (para 4-80).
If distance is 0.020 to 0.022 in. 0.508 - 0.559 mm), go to step 4.
Step 4. Check voltage on sensor output (white) lead at terminal block.
If 12 3 vdc are not measured, replace proximity sensor (para 4-80)
If 12 3 vdc is measured, go to step 5.
