IHI 16N warning buzzer

[Hawkeye]

Hi folks a newbie here. Hope someone can help me.
I have a ihi 16n mini digger that's got a warning buzzer and light coming on all the time
I have a service and parts manual and it doe's show me that there is a buzzer but no warning light. May have been an extra add on. No wiring help there.
That buzzer comes on when I first start it but that go's out. Always done that. This is what is buzzing. I can start the machine up no problem. maybe 1/10 minutes later it starts. All the fluid levels are okay. I have not found any record of a service reset. Have disconnected the radiator censor and grounded that. No luck.
Heeeeeeeeeeeeeelp.

Is their any designation on the lamp ? like an image of something ? .. Simple way would be to track the wires back from the bulb or buzzer and see what they are connected to
