Low Oil Switch
The low oil indicator system is designed to prevent engine
damage caused from insufficient engine oil. If the engine
oil level drops below a preset level, the yellow LED low oil
indicator light (Figure 47) illuminates and an oil switch will
stop the engine.
Figure 47
If the engine will not start and the low oil indicator is
illuminating, proceed as follows:
1. Check the oil level in the generator. If level is acceptable,
proceed to Step 2.
2. It is possible that the oil indicator float is stuck. Gently
rock the generator in a side-to-side motion to free the
float.
3. If oil level is correct and the float is not stuck, remove
the control panel and disconnect the 10-pin connector
(Figure 48).

4. Test for continuity between ground and the low oil switch
(A, Figure 49).
• If continuity is not measured, the switch is good.
• If continuity is measured and the oil level is good,
either the switch or the wiring is defective. Repair
the wiring or replace the switch.
