(2) Disconnect the positive (+) battery lead.
(3) Unhook the battery bands, and then re-move the battery from the watercraft. Checking the battery
Make sure that the battery case is not dam-
aged.
Make sure that the battery terminals are
not corroded or damaged.
Checking the battery voltage and charging
the battery
It is recommended to have a Yamaha dealer
check the battery voltage and charge the bat-
tery. Have a Yamaha dealer charge the bat-
tery as soon as possible if it seems to have
discharged. Keep in mind that the battery
tends to discharge more quickly if the vehicle
is equipped with optional electrical accesso-
ries. NOTICE: To charge a VRLA (Valve
Regulated Lead Acid) battery, a special
(constant-voltage) battery charger is re-
quired. Using a conventional battery char-
ger will damage the battery.
