Charging Coil Selection

Three types of coils are available:
Coil
Min/1000 rpm
2.7A 1.3
17A 6.5
26A 11
The 2.7A coil is only suitable for recharging a starting battery. Use the larger coils when powering accessories.
The regulator/rectifier has cooling fins integrated with the assembly. Install the regulator/rectifier in a place where the
ambient temperature is lower than 40°C (104°F) and there is a fresh supply of cool air passing over the cooling fins.
Mount the regulator/rectifier on the frame so that the vibration is 10 g (98 m/s
engine.
Install the appropriate fuse between the engine switch and the starter solenoid battery lead to protect the regulator
rectifier circuits: 30A for 2.7A and 17A coil; 40A for the 26A coil.

Oil Alert System (optional)
The Oil Alert System uses a float type switch located inside the crankcase. When the engine oil level falls below a safe
operating level, the float falls and the circuit is completed through the control box, grounding the primary side of the
ignition coil. The Oil Alert System is only recommended for use on equipment that is stationary while operating.

Oil Pressure Switch

The oil pressure switch is normally closed, completing the circuit between its terminal and ground.The circuit is opened
when the operating pressure is above 1.0 kg/cm
warning device such as a buzzer (12 Vdc 0.3A or above) or a lamp (12V 3.4W maximum).

Wiring Precautions

Connect the battery positive (+) cable to the positive terminal of the starter solenoid.
·
Connect the battery negative (–) cable to the engine crankcase or engine frame mounting bolt.
·
Do not route the battery cables on or near any hot, moving, or rotating parts, or sharp edges. Keep the battery
·
cables and electrical wires away from the fuel line.
Protect positive electrical connections with a cover or insulation.
·
Types with Oil Alert: Attach the negative battery cable from the battery directly to the outer mounting bolt of the
·
electric starter.
