Stop arm or crossing arm motor constantly running:
This might be happening because the stop arm does not shut close enough to the body in
order to give it the signal to stop. Open stop sign and loosen the nut holding it to the
assembly. Position sign a bit inward and tighten nut.
Strobe light not working:
Before replacing the strobe light, you should first check the fuse in the electrical
compartment and make sure it is not burned. Then, while key is in the ON position, and
switch for strobe light activated, look at the LED on the Strobe circuit board through the
lens and see if it is flashing. If the LED is flashing and the flashtube is not, the strobe
light is not defective only the flashtube (bulb) will need to be replaced (part # 92970). In
some cases, if the strobe is very hot, thermal shutdown takes place. During the time of
thermal shutdown, the led will still blink, yet the flashtube becomes inoperative. Allow
the strobe to cool down for fifteen minutes to see if that remedies the problem before
replacing any component.
To replace flashtube, remove top lens by twisting counter clockwise. Remove the
flashtube by squeezing the tabs on each side of the tube holder and pull it off.
Do not
touch the glass with your fingers.
Use gloves or a soft cloth. Note: The connector is
keyed to ensure proper orientation. Do not force. If the LED is out, remove screws and
lift strobe away from roof top. Check for current coming from body to ensure that it is
reaching the strobe light. If the wiring is good, then the strobe is defective and will need
to be replaced.
Transmission cannot be put out of park:
If the bus is equipped with a wheelchair lift for disabled passengers, there will be a
system that prevents the bus from being driven if the lift is not completely stowed and the
doors are not correctly closed and securely locked.
After these points have been checked, if the issue is still not solved, remove the top head
pad and make sure the switch is completely depressed by the door rod when latched. If
your vehicle is equipped with a second
switch on the lift door, you may need to check
connections to this switch as well.
