16-16 ELECTRICAL SYSTEM
Connect the 12 V battery to the main harness (see Self
-diagnosis Procedures in the Fuel System (DFI) chapter).
Connect a tester [A] to the battery terminals [B].
Start the engine, and note the voltage readings at various
engine speeds. But they must be kept the specified volt-
Tester (+) to
Stop the engine.
If the charging voltage is kept between the values given in
the table, the charging system is considered to be working
If the charging voltage is much higher than the values
specified in the table, the regulator/rectifier is defective
or the regulator/rectifier leads are loose or open.
If the charging voltage does not rise as the engine speed
increases, then the regulator/rectifier is defective or the
magneto output is insufficient for the loads. Check the
magneto and regulator/rectifier to determine which part is
