Peak voltage measurement
To check the electrical components or mea-
sure the peak voltage, use the special service
tools. A faulty electrical component can be
easily checked by measuring the peak voltage.
The specified engine speed when measuring
the peak voltage is affected by many factors,
such as fouled spark plugs or a weak battery.
If one of these factors is present, the peak volt-
age cannot be measured properly.
WARNING
When checking the peak voltage, do not
touch any of the connections of the digital
tester leads.
CAUTION:
• When testing the voltage between the ter-
minals of an electrical component with
the digital tester, do not allow any of the
leads to touch any metal parts.
• Place the watercraft in the water when
starting the engine, otherwise the engine
could be damaged.
