– Connect M-Tronic test lead to
multimeter
: Insert black plug (1) in the "com"
/ "ground" jack and the red
plug (2) in the "volt" / "ohm" jack
– Set multimeter to "diode test"
: Test diode on switchgear (3)
(microswitch) in accordance with
multimeter instruction manual
If the switchgear (microswitch) is
intact and the choke lever is set to
the "}" position, the following
target values will be attained:
– Measurement in direction of flow,
target value: 0.3 volts to 0.7 volts
– Move choke lever to position "F"
– slide control or lever for stop
function on control handle is not
pressed
– Reverse-biased measurement
Target value: 1.2 volts to infinity
– If target values are not attained,
replace M-Tronic wiring harness,

7.3.6 Checking the wiring
harness
– Carry out test preparations,
b 7.3.1
– Check contacts and operation,
b 7.3.3
– Move choke lever to position "F"
Checking the ground connection
: Measure the resistance between
blade receptacle (1) and
screw (2) at the control unit
(ignition module)
Target value: < 10 ohms.
If the target values are not
attained
– Check electrical leads for
interruption, e. g., cable
breakage – if necessary, replace
M-Tronic wiring harness, b 7.4.
