Yanmar GM10 switch panel problem

[Cuan]

Problem on my GM10 switch panel is that the buzzer started to make a shaky warbling sound when the ignition key was turned, and now doesn’t work at all. Also I managed to break the plastic cover completely.
So now I need either a new panel or a preferably a new buzzer. It’s tucked away down below so no need for full weatherproofing.
I would be grateful for any suggestions- I have seen some old threads suggesting automotive suppliers and forklift suppliers for switch panels, but I really do want to have an audible alarm for cooling and alternator alarms

I replaced the 12v. buzzer on my Beta 25 with an identical one from Ebay. The make was "Kingstate", but there's lots of others. Cost ~£3.

Thanks for the replies. That will do very nicely

When it comes to buzzers - near all are Piezo ... and you just have to know whether passive or active .... at the low pennies cost - you can afford to buy both types and see which works !!

Do you know whether Yanmar GM10 switch panel buzzer is active or passive? If not will do as suggested and try both.
Presumably the right type will work and the wrong type won’t. Function is for ignition on when key is turned, then as warning buzzer for charging and water temperature whilst engine is running

Almost certainly a plain vanilla 12v. active type.

Thanks I’ll get one

Bear in mind that the Yanmar buzzer is wired up with a hot 12v supply and the negative is pulled to 0v/gnd to sound the alarm. If you are just replacing the component this won't be an issue but if you wish to add to the alarm, bear this in mind.

I added an EGT sensor that triggers an alarm for overheat. I added a diode into the circuit (so it doesn't short out any of the Yanmar stuff) and it illuminates a big red LED and sounds the Yanmar buzzer if it goes into alarm. Sketch to follow if anyone else fancies the same project.

I recently replaced our dead Yanmar (A type) panel buzzer with one of these 12V 100 dB WARNING BUZZER for TRAILERS / INDICATORS / DOOR ALARM BUY 2 RECEIVE 3 | eBay . It's slightly smaller, but with some tape wrapped around it it fits nicely inside the housing of the Yanmar one.
