3) Automatic stop action test
Connect yellow terminal of motor to positive
battery terminal, and put a jumper
between Blue/White (Blue/Black) and Blue
terminals to see if motor output shaft comes
to a halt at a certain, not just any, angular
position. That position corresponds to start-
ing position of the blade. Using jumper,
stop motor a number of times to make sure
that motor stops at the same position each
time.

21-5. WATER TEMPERATURE METER
AND GAUGE
The water temperature meter is located in the
combination meter and its gauge unit on the
inlet manifold.
The gauge unit shows different resistance values
depending on the coolant temperature. This
causes a current f lowing through the temperature
meter coil to change, controlling the meter
pointer. That is, when the coolant temperature
is raised, the gauge unit resistance is decreased
with more current flowing through the meter
coil, raising the meter pointer upward from the
“C” position.
