Testing The Starter Circuit; Starter Relay - Rothewald 10002567 Mode D'emploi

generator coil. To test this coil, set the multimeter to the 2 kOhm
measuring range, perform a continuity test (see above), disconnect
the pulse coil, hold the test probe against the connections and
compare the measured value with the workshop manual. A
resistance that is too high indicates a line break, while one that
is too low indicates a short circuit. Now set the multimeter to
2 MOhms and measure the resistance between the winding and
earth – if it is not "infinite", there is a short to earth and the coil
must be replaced.

6.3.1 | Starter relay

The purpose of the starter relay is to reduce load on the cabling
and switches in the starter circuit. To test it, first disconnect the
thick cable leading to the starter. Insert the red test lead in the
VΩmAhFE jack, and the black test lead in the COM jack on the
multimeter. Select the 200 ohm measuring range and perform
continuity test (see above). Hold test probes against the relay
connections "Negative" and "Connection to switch". Turn on the
ignition. If necessary, actuate the safety switch on the clutch grip
or side stand, then press the starter button. The relay should now
"click" and a resistance of 0 ohms be measured. If the resistance is
greater than 0 ohms, the relay is faulty even if it clicks. Now select
the 20 V DC measuring range on the multimeter ( ). Disconnect
the "Negative" cable from the relay, hold the black test probe
against it, likewise disconnect the "Connection to switch" cable
from the relay and hold the red test probe against it. The measured
voltage should be 12 V. A lower voltage means a fault in the feed
cable, a plug, the starter button or a safety switch (voltage drop).
The switches can be tested by disconnecting their cable entries
from the circuit. Set the multimeter to 200 ohm measuring range,
perform continuity test (see above), hold test probes against the
cable entries and actuate the switch. If the measured resistance
is greater than 0 ohms, this indicates a faulty switch (if possible,
clean it, apply a little contact spray and then measure again).
