Description*#* Text*box* Explanation*or*Comment*1! Begin:!Troubleshoot!OR!Light! Start!the!diagnostic!process!for!a!work!order!on!an!OR!Light.!
2! Do!all!bulbs!illuminate?! Provide!the!light!with!power!and!observe!whether!or!not!all!of!the!bulbs!produce!light.!
3! Is!voltage!delivered!to!nondfunctional!bulbs?! If!some!of!the!bulbs!do!not!illuminate,!it!could!be!due!to!issues!with!the!bulb!or!the!power!supply.!Use!a!multimeter!to!check!that!appropriate!voltage!is!being!delivered!to!the!bulb!housings.!!See!BTA!skills!on!Electrical!Lighting/Indicators.!
4! Troubleshoot!bulb!connections!!


If!bulbs!do!not!illuminate!and!are!not!receiving!power,!then!there!may!be!something!wrong!with!the!connections!from!the!bulb!housing!to!the!bulb!itself.!Inspect!the!housing,!clean!any!residue!on!connections!and!mend!poor!connections.!
5! Check!continuity!of!power!supply!wires!to!bulb!housings! Ensure!that!the!bulb!housings!are!connected!to!the!power!supply.!Use!a!multimeter!to!check!the!continuity!of!the!wires!running!from!the!power!supply!to!the!bulbs.!!
6! Troubleshoot!power!supply! If!the!device!is!connected!to!power!but!does!not!turn!on,!there!is!a!problem!with!the!power!supply.!This!could!be!a!problem!with!the!wiring!or!connections!within!the!device.!See!BTA!skills!on!Power!Supply.!
7! Are!bulbs!incandescent?! Incandescent!light!bulbs!use!a!tungsten!filament!encased!inside!a!glass!housing.!
8! Are!bulbs!halogen?! Halogen!bulbs!have!a!tungsten!filament!encased!inside!a!quartz!housing.!The!housing!is!much!closer!to!the!filament!than!in!incandescent!light!bulbs.!
9! Are!bulbs!fluorescent?! Fluorescent!bulbs!have!a!sealed!glass!tube!filled!with!mercury!and!an!inert!gas.!!
10! If!bulb!type!is!unknown,!use!only!the!voltage!capacity!to!determine!the!replacement! Reference!BTA!skills:!Unit:!Lighting/Indicators,!Skill:!Fixtures.!
11! Use!replacement!bulb!from!manufacturer!if!available! Acquire!the!bulb!designed!for!the!OR!lamp!unit!by!the!same!manufacturer!as!the!unit.!Use!this!replacement!bulb!to!replace!any!
