Winterfront Cover; Stop Sign Blade Failure - Blue Bird TC/2000 Owner's Manual

STOP SIGN BLADE FAILURE

Problem:
Lights do not function.
Areas to Check:
1. Check to insure that the light bulb is working.
2. Check to insure that the ground strap is secure.
3. Check to see if 12V is being supplied to the light bulb.
It is important to note that there have been improvements made to the socket and pigtail. The improve-
ments are as follows:
A. Screws versus rivets make replacement possible with a common nut driver.
B. A two-wire socket and pigtail eliminated the braided wire ground strap which on occasion failed in
the field. This will help insure that the ground is intact throughout the operation and life of the sign.
C. Lower temperature protection (minus 40-wire and vinyl tubing) have been added to insure a broader
temperature range in northern and southern climates.
Problem:
Fading to the blade surface.
Areas to Check:
1. Steel blades are painted with a red paint, which are prone to bleaching due to the pigments. If the
blade becomes faded possible solutions are to repaint or replace the blade. Specialty recommends the
replacement of the blade due to the labor savings and cost efficiency. Approximate cost of replace-
ment blades on a steel blade is $8-10 depending on the quality.
2. Aluminum reflective signs have improved in technology to the point where blades in southern expo-
sures are now lasting five to seven years. This is due to ink improvements where the pigmentation in
the inks actually darkens over the life of the sign. Replacement now is due to sub-straight failures on
Engineering grade versus ink failures as in the past. Decals are available for Engineering grade and
high intensity sign runs you approximately twice as much as a steel blade. All or our products; air,
vacuum and electric are available with a high intensity face.

WINTERFRONT COVER

The winterfront cover design for charge-air-cooled TCFE engines beginning in 1991 is slightly different
from previous winterfronts. A minimum of 120 square inches of area must remain open at all times. There-
fore, do not attempt to cover the air inlet holes in the headlight panel while the winterfront cover is on the top
grille panel.
Keep a watchful eye on the engine coolant temperature gauge at all times when the winterfront is in
place. If the engine temperature begins to rise above normal and/or the shutters begin to stay open, remove
the winter front cover.
