Testing the starter motor
This test detects excessive current consumption of the starter motor. Excessive current consumption
of the starter motor leads to an overload of the battery and thus shortens its life. This test should only
be carried out if the battery load test was previously completed with "OK".
For testing the motor should have normal operating temperature.
•
Connect the test device to the vehicle battery with the correct polarity.
•
Press the test button for max. 10 seconds and note down the voltage value while keeping the
•
test button pressed.
Disconnect the engine ignition cable from the spark plug so that the engine does not start
•
when starting.
Now try to start the engine. Make a note of the voltage during the starting procedure.
•
Compare the two voltages with the yellow table printed in the display (STARTER TEST). The
•
upper row of the table refers to the "LOAD VOLTS" i.e. the voltage measured during the load
test with the unit. Below this voltage value the table shows the corresponding minimum star-
ting voltage (MIN. CRANK VOLTS).
Example: You measure a voltage of 10.4 V during the load test and the voltage collapses to 9.5 V du-
ring starting. According to the table a starting voltage of up to 8.2 V is acceptable. The starter engine is
ok. If a starting voltage of less than 8.2 V is measured, a short circuit in the starter, a fixed bearing in
the starter etc. could be the reason for excessive power consumption.

Malfunctions on the device
If it can be assumed that safe operation is no longer possible, the device must be taken out of operati-
on and secured against inadvertent operation.
This applies if:
the unit shows visible damage.
•
the device is no longer functional.
•
parts of the unit are loose or loose.
•
the connecting cables show visible damage.
