5) Brake Fluid Level Warning
Light
The light is connected to the brake
fluid level sensor that is incorporated
in brake fluid reservoir cap.
If
brake fluid decreases to less than the
specified volume in the reservoir, the
sensor is actuated and the light comes
on while the engine is running.

a. For checking if bulb of brake fluid
level warning light is burned out,
make sure that the warning light
glows when ignition-starter switch
is initially turned to "ON" and it
goes out when engine is running.
b. If brake fluid reservoir is inclined
or vibrated abnormally, the warning
light may be lighted momentarily
even fluid level is above the speci-
fied limit.
6) Stop Light Warning Light
, I
The ligb t is connected to the stop light
checker. Thb checker consists of a
reed switch and magnet coils
CD
and
® .
3S
shown in figure. Under normal
conditions. the magnetic fields are
generated in the magnet coils
CD
and
C1\
hy the current flowing through
each lamp while the stop lamp switch
is ON. These magnetic fields cancel
each llther because the coils turn in
directions llpposite tll each other. As a
result, the reed switch will remain
OFF. and the warning light is OFF.
If
either the left or right hand side
stop lamp fails, current will flow
through only one magnet coil, and
the resultant magnetic field causes the
reed switch to turn ON. Therefore. the
warning light will remain lighted as
long as the brake pedal is depressed.
