This system allows starting the engine by temporarily bypassing the oil pressure shutdown feature.
When the engine starts it monitors the required low oil pressure. It waits and if minimum oil pressure is
not reached safely it will shut engine off. If the pressure is correct the engine will continue to run
through the oil pressure switch closure. This overrides the ignition switch on power enabling it to shut
the engine off with the ignition switch still on. The ignition switch simultaneously also retains the ability
to shut the engine off. With this control the oil pressure switch never switches any high currents which
assures its longevity while still maintaining a 40 amp capacity ignition circuit.
Our units manual override switch is provided to bypass and/or test the engine oil pressure switch. By
automatically monitoring the startup oil pressure rise it is unnecessary to crank the motor excessively
with the ignition off in an attempt to obtain enough oil pressure to close the switch and allow the car to
start. This procedure only drains the battery, overheats the starter and tends to flood the motor and
wash the rings
