Oil Pressure Switch; Engine Run Solenoid - Toro Reelmaster 2000-D Service Manual

Oil Pressure Switch

The engine oil pressure switch is located on the cylinder
near the dipstick and oil filter. It is a normally closed
switch and opens with pressure. The operating range for
the switch is 2.9 to 5.7 PSI (0.2 to 0.4 kg/cm
Testing with the engine off
1. Turn the ignition switch to the ON position. The oil
pressure lamp should be on.
2. If the lamp is not on, disconnect the gray wire from
the switch and ground the wire to the engine block.
3. If the lamp comes on, the oil pressure switch is bad.
4. If the lamp does not come on after step 2, check the
circuit wiring and indicator light.
Testing with the engine running
1. If the lamp is on with the engine running, shut off the
engine immediately.
2. Disconnect the gray wire from the switch.
3. Turn the ignition switch to ON. The oil pressure lamp
should not be illuminated.
4. If the light is still on, check the oil switch circuit wiring.
5. Return ignition switch to OFF and connect the gray
wire to the switch.
See the Briggs & Stratton/Daihatsu Engine Repair
Manual for engine oil pressure testing procedures.

Engine Run Solenoid

The engine run solenoid must be energized for the en-
gine to run. The solenoid is an integral component of the
injector pump and has a red/black wire attached to it.
The Standard Control Module monitors the operation of
the engine run solenoid. If the ignition switch is either in
the ON or START position and the correct switch inputs
(seat, parking brake, etc.) are received, the Module en-
gine run output LED should be illuminated.
