Checking Th Erelays - Yamaha WR450FB 2012 Owner's Service Manual

f. If charging requires more than 5 hours, it is
advisable to check the charging current after
a lapse of 5 hours. If there is any change in
the amperage, readjust the voltage to obtain
the standard charging current.
g. Measure the battery open-circuit voltage af-
ter leaving the battery unused for more than
30 minutes.
12.8 V or more --- Charging is complete.
12. 7 V or less --- Recharging is required.
Under .12.0 V --- Replace the battery .

Charging method using a constant volt-
age charger
a. Measure the open-circuit voltage prior to
charging.
TIP _ _ _ _ _ _ _ _ _ _ _ _ _ _
Voltage should be measured 30 minutes after
the engine is stopped.
b. Connect a charger and ammeter to the bat-
tery and start charging.
c. Make sure that the current is higher than the
standard charging current written on the bat-
tery.
TIP _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
If the current is lower than the standard charg-
ing current written on the battery, this type of
battery charger cannot charge the VRLA (Valve
Regulated Lead Acid) battery. A variable volt-
age charger is recommended.
d. Charge the.battery until the battery's charg-
ing voltage is 15 V.
TIP _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
Set the charging time at 20 hours (maximum).
e. Measure the battery open-circuit voltage af-
ter leaving the battery unused for more than
30 minutes.
12.8 V or more --- Charging is complete.
12. 7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery .

CHECKING THE RELAYS
Check each switch for continuity with the pock-
et tester. If the continuity reading is incorrect,
replace the relay.

1. Disconnect the relay from the wire harness.
2. Connect the pocket tester
(n
