Propane fueling issue:
The vehicles will be fast or slow to fill depending on the weather and the equipment of
the propane dispenser. The propane goes through the engine and returns back into the
tank, heats it up and causes pressure to build. If the dispenser used to fill up is old, it will
not be able to fight the pressure and easily fill up. If there is more than 20 lbs difference
in pressure between the dispenser and the tank, the vehicle will allow fuel to fill the tank,
however, very slowly. You should make sure to find a fuel location with pumps that are
allowing the pressure differential to open the check valve and fill the fuel system easily.
Radio not working correctly:
If you have the original radio from GM or Ford, contact your Micro Bird dealer for
instructions.
If is is an aftermarket radio: First, press the reset button on the front of
radio to check if it solves the issue. If not, contact your Micro Bird dealer for
instructions.
School bus illuminated sign has burned light bulbs:
The light bulbs are located behind the access panel in front and in rear of the vehicle. On
G5 model vehicles, they are visible when access door is lifted. On MBII models, the
lights will be lower behind the panel and fixed to the structure of the bus. The light bulbs
need to be replaced by the same amperage (use #105 light 12.8V) to ensure there is no
overheating.
School bus package not opening or closing (stop arm, x-arm or 8 way flashers)
If the yellow flashers are working, but when the entrance door is opened the red flashers
do not work as well as the stop arm or crossing arm not deploying. See wiring
schematic... and make sure the diode is on tab 9 (with a sequencial system) or 10 (with a
non sequencial system) of the in power module in the electrical compartment. Please
refer to the wiring diagrams supplied with your bus.
If you are having an issue with either of these components activating on the road or not
shutting off, you may want to check the adjustment of the microswitches above the
entrance door as these control the opening and closing of the doors and will tell the motor
when to stop. If your doors are not closed tightly, you may adjust the entrance door and
its switches as shown on page 38 of this manual. If the stop arm or crossing arm still
activate and the 8 way flashers are off, check wiring of stop arm or crossing arm. If you
cannot find the issue, the part itself may be defective. Contact your dealer for help.
