The oil level switch is designed to shut the engine off in the event the oil level drops. The oil level switch is
located inside the engine crankcase.
A clogged or stuck oil level switch will allow the engine to run without or with a low oil level which can cause
damage to the engine. An engine with sludge oil caused by lack of maintenance can cause an oil level switch
to stick. Checking oil level prior to running the engine is good maintenance practice as well as changing
engine oil frequently.
Inspection
Check the continuity between the switch and switch
body with an ohmmeter.
1. Hold the switch in its normal position. The ohmmeter
should read zero resistance.
2. Hold the switch upside down. The ohmmeter should
read infinity (∞) resistance.
3. Inspect the float by dipping the switch into a
container of oil. The ohmmeter should go from zero
to infinity as the switch is lowered.
