Disconnect the starting enrichment thermal valve
connector if applicable. (See t o the diagram at right.)
I
Check that there is voltage between battery line
(+I
and ground line.
Check continuity between ground and frame.
Check that there is battery voltage between voltage detection line
(+I
and
ground wire when the ignition is ON.
Check that the resistance of the coil is within the specified range.
Check that the resistance of the coil is within the specified range. (Because
the lighting system effects the resistance value, follow the steps below.)
With integrated chargingllighting coils (charging and lighting
shared by a single coil), disconnect the coil output connector
when measuring resistance. The headlight resistance will be
included in the ohmmeter measurement if the connector is not
disconnected. (If the headlight connector is connected, the
measured resistance will be smaller, because the headlight
resistor is connected in parallel.)
For lighting systems whose headlight connector is
connected to a resistor when the headlight is turned OFF,
either disconnect the handlebar switch connector or the
lighting outprrt line of the chargingllighting. (Refer t o the
diagram at right.)
If the readings taken based on the chart above reveal that
there is an abnormality, check the following:
-
Battery wire Broken wire harness (repair or replace)
Ground wire
-
Broken wire harness (repair or replace)
.
Charging coil
-
Check the charging coil of the alternator
Chargingllighting coil - - Checkthe chargingllighting coil of
the alternator
If the resistance value of the alternator is normal (i.e., the
resistance value measured by the above method is different
from the alternator resistance)
Check for a broken or shorted wire harness between the
regulatorlrectifier and alternator, or for a poor connection
at the alternator connector.
