Oil Pressure Switch (Workman 2100/2110)
The oil pressure switch is located on the mounting
adapter for the oil filter. It is a normally closed switch and
opens with pressure.
Oil pressure switch testing
1. Turn the ignition switch to ON. The oil indicator light
should be on.
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 bad.
4. If the light does not come on after step 2, check the
indicating circuit (see Electrical Schematic).
If the lamp 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 pressure lamp
should go out.
4. If the light is still on, check for short circuiting in the
indicating circuit (see Electrical Schematic).
5. Refer to the Briggs and Stratton Repair Manual for 4
Cycle, V–Twin Cylinder, OHV Head Engines for addi-
tional testing information.
