Oil Pressure Switch (Workman MDX)
The oil pressure switch is located on the mounting
adapter for the oil filter.It is a normally closed switch that
opens with pressure.
Oil pressure switch testing
1. Turn the ignition switch to ON. The oil indicator light
on the dash should be illuminated.
2. If the light is not on, disconnect the wire from the oil
pressure switch and ground the wire to the engine block.
3. If the light comes on, the oil pressure switch is faulty.
4. If the light does not come on after step 2, check the
indicating circuit (see Electrical Schematic in Chapter 8
-- Electrical Diagrams).
If the oil indicator light comes on with the engine
running:
1. Shut off the engine immediately.
2. Disconnect the wire from the oil pressure switch.
3. Turn the ignition switch to ON. The oil indicator light
should go out.
4. If the light is still on, check for short circuiting in the
indicating circuit (see Electrical Schematic in Chapter 8
-- Electrical Diagrams).
5. Refer to the Briggs and Stratton Repair Manual for 4
Cycle, V--Twin Cylinder, OHV Head Engines for addi-
tional testing information.
