range 20 V DC on the multimeter. Disconnect positive and negative leads from
the consumer and hold the black test probe against the negative and the red
one against the positive lead. The measurable voltage should be 12 volts
–
readings below this suggest energy losses.
4.2 Leakage currents
Leakage currents at the ignition lock, switches, connectors and cables can
"suck" the power from a bike battery until sooner or later it becomes totally flat.
A leakage current can be revealed with a test lamp or by using the multimeter to
measure current. Remember that, to avoid overheating, your multimeter must
never be subjected to loads in excess of 10 A (see safety instructions). The
multimeter must therefore on no account be used to measure current on the
positive lead to the starter, on the thick battery cable to the starter relay or at the
alternator.
In order to detect a leakage current, first turn the ignition off and disconnect the
positive cable from the battery. Select the 10 amp measuring range on the
multimeter, insert the red test cable in the 10 ADC jack and the black one in the
COM jack, then hold the red test probe against the positive cable and the black
test probe against the battery's positive terminal. If a current can be measured,
this indicates that there is a leakage current. The source of the leakage current
can be narrowed down by removing fuses from the bike one by one. The circuit
whose fuse cancels out the reading on the measuring instrument is the source
of the leakage current and must be investigated thoroughly.
Faulty diodes can also cause a leakage current by opening in an uncontrolled
manner. This can be tested using the "Diode test" function on the multimeter.
