(12) Battery The electrical system has two separate circuits.
Charging circuit
Starting circuitSome of the electrical system components are used in more than one circuit. The following items are common in each of the circuits:
Battery
Circuit breaker
Cables
Wires for the batteryThe charging circuit is in operation when the engine is running. An alternator converts mechanical energy to electrical energy for the charging circuit. A voltage regulator in the circuit controls the electrical output in order to keep the battery at full charge.
The disconnect switch, if equipped, must be in the ON position in order to let the electrical system function. There will be damage to some of the charging circuit components if the engine is running with the disconnect switch in the OFF position.
If the engine has a disconnect switch, the starting circuit can operate only after the disconnect switch is put in the "ON" position.The starting switch is in operation only when the start switch is activated.The charging circuit is connected through the ammeter. The starting circuit is not connected through the ammeter.Automatic Shutdown System

The engine will shut down if the following conditions continue for more than 10 seconds while you start the engine or for 2 seconds while you operate the engine:Coolant temperature exceeds the following values: All engines ... 110° 3°C (230° 5°F)Engine oil pressure falls below the following values: Engine oil pressure switch that is located on the valve mechanism cover ... 29 kPa (4.27 psi)Engine oil pressure switch that is located on the cylinder block ... 98 kPa (14.22 psi)Note: There is no automatic shutdown for low coolant level.Note: The capacity of the diode must be 3 A with a reverse voltage of 600 V.Note: The rated current draw of the engine oil pressure switch is 0.42 A (5 W maximum bulb).Note: If necessary, a delay fuse should be used for replacement.Charging System Components
