TACHOMETER
The tachometer is used to measure the engine
speed. Engine speed must be known in order to:
-Adjust the idling speed
-Check the ignition
-Adjust the timing
-Check the adjustment
1. Press the tact switch to light the RPM indicator.
2. Connect the inductive pick-up to the First
cylinder.
3. Connect the red clip to the positive battery
terminal (+) and the black clip to the negative
battery terminal (-). (See figure 1).
4. Start the engine and read off the rpm from
the display. Compare the rpm with the figure
recommended by the vehicle manufacturer.
Should any deviations
appropriate adjustments.
VOLTMETER
The voltmeter can be used to check the battery
voltage and the supply voltage to the various
consumers, e.g. lamps, etc.
1. Testing of battery voltage under starting
current load.
a. Disconnect the ignition by pulling the plug
off terminal 1 (1,D,RUP,-) on the ignition coil.
b. Press the tact switch to light the VOLT
indicator.
c. Connect the black clip to the negative
battery terminal (-) and the red, green clip to
the positive battery terminal (+). (See figure
3)
d. Have the car started by an assistant.
e. Read off the voltage from the LED display.
If less than 9V is indicated have the battery
checked professionaily.
2. Measuring the voltage at consumers (e.g.
8
be found, make
lamps).
For this test switch on the consumers.
a. Connect the black clip to the negative
battery terminal (-) and the red clip to the
positive battery terminal (+).
b. Connect the green clip to the positive
terminal on the consumer.
c. Switch on the consumer and read the
voltage from the LED display. If the voltage
is too low, this indicates leakage through
the respective leads or connections. This is
frequently indicated by heating of connecting
terminais, switches or parts of the leads.
d. Should the voltage drop be greater than
that specified in your owner's manual, it is
advisable to consult a garage.
