Turn ignition key switch ON. Oil pressure lamp and
buzzer should be on.
If lamp and buzzer are not on:
1. Disconnect wire from oil pressure switch and touch
wire to a good ground, such as the engine block.
2. If lamp and buzzer come on, replace switch.
3.
If lamp and buzzer do not come on check wiring

between switch, lamp and buzzer for continuity.
If lamp and buzzer are on with engine running:
1. Shut off engine immediately.
2.
Check switch by disconnecting wire with ignition
switch in ON position. Light should go out.
3. If light is still on, check for short circuit in wiring.
4. Install test gauge in engine oil pressure switch port.
Start engine and check oil pressure. If engine oil pres•
sure is good, replace switch. If engine pressure is low,
DO NOT operate the engine.
