APPENDIX III
TESTING AND REPAIRING THE SL - 40X
This section includes information to repair the SL - 40 series flashlights. A multimeter and
Phillips screwdriver will be needed to perform most repairs and troubleshooting. Some repairs
may require the use of a soldering iron.
Testing/Replacing the Lamp
1. The lamp is held in place by the lamp ring.
a. Hold the body of the flashlight firmly.
b. Press down on the lamp ring and rotate it counter clockwise.
NOTE : Use care and attempt to avoid stressing the lamp housing where it connects to
the body of the flashlight. An alternate method of securing the lamp housing is to
move the lamp housing to a position 90 degrees from the flashlight body. Place
the back of the lamp housing on a sturdy work bench or desk top to provide
leverage while the lamp ring is being turned.
c. Remove the lamp from the lamp housing and slip the wire leads from the bulb leads.
2. Test the lamp while it is disconnected from the flashlight
a. If the lamp is the
sealed beam
type test as below.
1. Place a multimeter into the continuity position.
2. Place the red lead on one of the lamp contacts
3. Place the black lead on the other lamp contact.
4. The meter should beep and indicate continuity.
b. If the lamp is the new style with a
plastic reflector and screw-in bulb
test as
below.
1. Test the bulb by using a multimeter in the continuity position.
2. Place the red meter lead on one of the bulb leads.
3. Place the black meter lead on the other bulb lead.
4. The meter should beep and indicate continuity.
3. If the meter does not indicate continuity the bulb will need to be replaced.
a. If the SL-40 was equipped with a sealed beam bulb it will need to be upgraded with
the PAR-36 Lamp Retrofit Kit P/N : 40107.
1. The kit contains 3 lamp spacers which are required to support the new plastic reflector
system.
a. Place the lamp spacers (beveled edge down) into the slots provided in the head.
b. The spacers' support surface should be located 1/8" below the edge of the lamp
housing (see illustration).

2. The new black lamp ring will be used at the end of this procedure to secure reflector
and bulb in place.
b. When the SL-40 is equipped with the new system follow the instructions below.
1. Replace the bulb(s) by unscrewing the plastic threaded bulb socket from the plastic
housing.
a. Pull the old bulb straight out from the socket.
b. The bulb is labeled with voltage and wattage.
c. Replacement bulb information is printed on the back of the reflector assembly.
2. Replace the bulb by aligning the pins of the new bulb with the holes in the socket and
seat the bulb firmly.
3. Wipe off any fingerprints from the bulb with a tissue and alcohol.
4. Screw the socket back into the reflector assembly.
a. The socket can be fully seated in the flood reflector assembly.
b. The socket can be adjusted in the spot reflector assembly.
1. Turn the SL-40 on and shine it on a wall approximately 10 feet away.
