2. Connect the positive test lead to the pin No. 9 and
the negative test lead to the pin No. 6 of the display
unit connector and measure the VDC. The mea-
surement should be approx. 0 V at full speed and
at idle.

SPEED SIGNAL OUTPUT FROM DISPLAY UNIT
As the multi tester can not read exact voltage
which is fluctuate with high frequency, it just
shows average value(7V) as shown in the picture
when the wheel is turning while it shows 0V or
14V when the wheel is stopped.
The speed change can not be read by multi
tester as the speedometer in the dash can read it
according to the frequency(Hz) change.

SPEED SIGNAL OUTPUT FROM SPEED SENSOR
The output voltage from speed sensor is shown
in the graph above. However, it is hard to read
with normal multi tester as its average is zero
and its peak voltage capacity is small due
to its curved top and bottom. Therefore, it is
recommended to measure the display unit output
voltage or instrument panel input signal. Because
the display unit amplifys this input signal to 0 ~
14V and modulates the sine curve to a square
wave as shown in the former remark box.
