Engine will not start:
If the engine will not start and you hear a continuous buzzer, this may be caused by an
interlock installed on the rear door or the passenger doors. Make sure the doors are
unlocked.
If situation persists after the rear door has been unlocked, make sure the switch is
releasing properly from mechanism by pushing on it and releasing it a few times. The
buzzer should stop when plunger is released. If situation happens with the passenger
entrance doors, the issue might be with the switch fixed behind the red handle which
releases mechanism when unlocked.
In any of these situations, if you are on the road when this happens, you can bypass the
system by removing the interlock fuse. Refer to the sticker behind the electrical
compartment door for location or refer to the wiring diagrams supplied with your bus.
You will then be able to drive back to the garage to have this checked.
Entrance doors will not close tightly:
The mechanism is made of a single assembly with oppositely threaded spherical bearing
rod end connectors on each end providing simple link length adjustment without
disassembly. Simply loosen the lock nut, turn the rod and retighten the nut when the
adjustment is satisfactory. You may also want to adjust the microswitches to allow a
longer course of the doors and make them sit tighter against the body.
**Attention, if you misadjust the microswitch, the motor will keep running trying to shut
the doors even closer as they are already sitting on the body. If door leaves are tightly
shut, the stepwell light will turn off when doors reach the closed position.
If the doors stop opening or closing while they are moving, check the condition of the
system main components: bearings gears, ball and socket joints, motor and sensors. See
if there is any foreign object struck underneath the sprocket or motor preventing the
system to complete its motion.
