Electrical System
Stop, Tail, Turn, Backup, and Hazard Lights
A combination light assembly is mounted in the rear corner panels. This light assembly includes an am-
ber turn signal light, a combination stop and tail light, and a backup light. The turn signal light also acts
as a hazard warning light. In addition, stop lights, or combination stop and tail lights, are positioned on
the air conditioner compartment cover.
The remaining turn signal lights are mounted on the sidewalls and in the front headlight bezel assem-
blies so that the turn signal indicators are visible from both the front and the side of the coach.
The hazard warning system uses the front, side, and rear turn signal lamps. The system is energized
when the hazard switch in the driver console panel is moved to the ON position, at which time the desig-
nated signal lamps begin flashing.
Stop Lights
The stop light system consists of the rear corner left-hand and right-hand stop lights, high-mounted,
stop lights on the air conditioner door, and air actuated switches. When the service brakes are applied,
air pressure energizes the stop light switches, that close to energize the circuit to the stop lights and the
stop light indicator light. The rear stop light circuit is not routed through the multiplexer. This is a safety
measure in case of multiplexer failure.
Lamp Component Replacement (Disposable Type)
The stop and tail lights, turn signal lights, and backup lights use LEDs instead of conventional bulbs.
These units do not have replaceable bulbs. If the light is defective, replace the entire lamp assembly.
The flange mounted lamp assemblies are retained by screws. Replace the lamp assemblies as follows:
1. Turn the battery disconnect switches in the battery compartment to the OFF position to avoid the
possibility of an accidental short.
2. Remove the mounting screws and pull the lamp assembly away from the coach body.
3. Disconnect the lamp from the wiring by pulling the electrical connector away from the lamp.
4. Replace the lamp with a new one. The defective lamp assembly may be repairable by the manu -
facturer.
Stop Light Switches
The stop light switches (Figure 9- 54 ) are combination
electrical/air operated switches which operate in con -
junction with the brake system valves to complete an
electrical circuit when the brakes are applied. The front
and rear brake switchs are located under the driver’s
platform.
When checking the stop light switches, perform a
leakage test. With the brakes applied, no air leakage is
permitted at the stop light switches.
