USEFUL INFORMATION FOR REPAIRS
ELECTRICAL PANEL
The electrical panel is installed in a closed compartment above the driver. The wires are
coded by number and by color. In this compartment, depending on the options present in
your bus, you will find some or all of the following components. For more information,
please refer to the wiring schematic of each component supplied with your bus.
Solenoid or power relay:
feeds all components of electrical box.
Fuse boxes:
labeled IFH for Ignition fuse holder, BFH for Battery fuse holder and NFH
for noise suppression fuse holder. A sticker listing fuse locations is installed behind the
electrical compartment’s door.
Relays for different options:
Relays for all body options are installed in the electrical
compartment. Additional relays for the noise suppression switch and rear door interlock
will be located under the hood. Noise relay will be on the left side near the HVAC and
the interlock relay will be tied in our body harness on the right side.
Bus scan module (
child detection system). This module is always disconnected on
delivery to the dealers to make sure the driver picking up the bus does not have to
deactivate the system while getting to his destination. It needs to be plugged in during
bus preparation.
In power module:
controls the school bus package (8 way lights, stop arm, crossing
arm).
Air conditioner relays:
Relays for the MCC systems are installed in the electrical
compartment on our G5 model busses and will be located on the wall behind the driver,
underneath the grey pad, on our MBII model busses. On ACC systems, they can be
located in either of these areas or on the evaporator itself
For any question or repairs to the electrical system, please refer to the wiring
schematic supplied with your vehicle and contact your Micro Bird dealer for further
help.
