Thanks for your reply, Norm.

Yes from the Honda GXV390 User Manual:
"OIL ALERT® BUZZER (oil alert type only)
The OIL ALERT buzzer will warn you before the engine oil level falls below the safe operating limit. If the buzzer sounds, stop the engine
immediately and add oil."

My query relates to the sound, as mine is a "ting", definitely not a "buzz", which is why I was wondering if anyone was familiar with the sound of the oil alert buzzer .

I will disconnect the oil alert switch tomorrow.

Cheers
