Operation

OIL PRESSURE GAUGE
^ When the ignition switch is at the "ON" position, the oil pressure gauge is activated.

^ When oil pressure is high, the internal contacts of the gauge unit are kept closed for a longer period of time. This causes more current to flow in the circuit, and the gauge pointer swings to the high pressure side.

^ When oil pressure is low, the internal contacts of the gauge unit open in a shorter period of time. Therefore, there is less current flowing in the circuit and the gauge pointer swings to the low pressure side.


PRESSURE METER
^ When the ignition key is set to the "ON" position, the gauge indicator will be at "0".

^ When the engine is started, the indicator will move from "0" to the minus (-) side, and then, as the boost level increases, it will move to the plus (+) side.
