15.3.4 Batteries
The batteries are lled with an acid at adensity of 1.28g/ml by the manufacturer and charged suciently for immediate use. When the
starting power is insucient, recharging is required.
Charging
• The battery must be recharged if the open-circuit voltage is below 12.5V due to alonger storage time. The open-circuit voltage
shall be checked after 2–4 quarters from the production date. If the open-circuit voltage is below 12.5V, the battery must be
recharged before alonger storage time to alevel from 12.7 to 12.8V. The open-circuit voltage shall be measured with adigital
multimeter. The measurement should be made at about 20°C.
• Ensure good ventilation of working areas.
• Use suitable DC chargers only.
• Connect the plus pole of the battery with the plus output of the charger; connect the minus pole in asimilar way.
• Turn on the charger after the battery is connected and turn it o after it is recharged.
• Recommended charging current: 1/10 battery capacity in Amperes (Ah).
• If the acid temperature exceeds 55°C, interrupt the charging.
• The battery is fully charged when the charging voltage does not increase further in the course of two hours.
• When the charging is completed, always measure the open-circuit voltage (do it no sooner than 1hour after the charging).
Removal
• While disassembling, rst disconnect the cable of the negative (–) pole and then of the positive (+) pole. Never disconnect the bat-
tery when the engine is running.
Installation
• Remove the protective cover of the plus pole only in the machine while connecting the pole terminals and put it on the pole of the
removed battery to prevent short-circuits.
• Clean the poles and clamps and apply athin layer of grease on the poles.
• First, attach the plus poles and make sure the clamps are rmly attached.
• Leave at least one degassing vent free.
15.3.5 Alternator replacement
The alternator is apart of the engine. In the event of afault, contact the engine manufacturer Yanmar.
15.3.6 Starter replacement
The starter is apart of the engine. In the event of afault, contact the engine manufacturer Yanmar.
