Spot Lamp: Testing and Inspection
SPOT LAMP ASSEMBLY - POLICEIF SPOT LAMP DOES NOT LIGHT
1. If both spot lamps are inoperative, check fuse F (spot lamp master). Refer to Wiring Diagrams for fuse locations. If fuses are OK, refer to Step 4. If fuse(s) are faulty, replace as necessary.
2. If the left spot lamp is inoperative, check fuse X.If fuse is OK, refer to Step 4. If fuse is faulty, replace as necessary. If fuse blows again, find short to ground. Refer to Wiring Diagrams for circuit information.
3. If the right spot lamp is inoperative, check fuse Y.If fuse is OK, refer to Step 4. If fuse is faulty, replace as necessary If fuse blows again, find short to ground. Refer to Wiring Diagrams for circuit information.
4. Check for B+ power at the spot lamp bulb with switch turned ON (Refer to ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/SPOT LAMP - REMOVAL). If there is B+ power at the spot lamp bulb connector, replace bulb. If there is not B+ power present, refer to Step 5.
5. If there is not B+ power present at the spot lamp with the switch turned on, check circuit for an open. Possibly the connector in the A-pillar. Refer to Wiring Diagrams for circuit information.
6. If there is B+ power at the spot lamp connector, and no B+ power at the spot lamp bulb, then the switch is defective within the spot lamp assembly and the entire unit must be replaced. (Refer to ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/ SPOT LAMP - REMOVAL).
7. If lamp still does not light, remove the handle (Refer to 8 - ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/SPOT LAMP - REMOVAL), and check the contact on the shaft end of the head assembly into the handle to make sure the contact is not damaged.
IF SPOT LAMP IS HARD TO TURN
1. Check that the head housing clamping screw creates just enough drag to hold the spot lamp head in position in windy conditions. Extreme drag will require more force on the handle to move the spot lamp head and cause damage.
