Yanmar Buzzer replacement

[pjacobs]

Hi:
I'm new to the forum and sail an Albin Vega 27 in the Southern Vancouver Island area.

I found the forum through a search for a replacement plug for my AutoHelm ST2000. Many thanks to Alex Rogers for that valuble piece of info. /forums/images/graemlins/grin.gif

Now I'm looking for a buzzer replacement for my Yanmar 2GMF control panel. Does anyone have information that may be of help?

Thanks!

Hi,

Whatever you do don't buy a Yanmar spare replacement, they about £50 here in UK. I recentl replace mine with a buzzer from an elecrical supplier for £1.29- Maplin. Have a look at: http://www.maplin.co.uk/Module.aspx?ModuleNo=3219&doy=20m1&criteria=buzzer This is also slightly smaller than the Yanmar one so will fit in the hole but you have to make a simple bracket. The whole job took under an hour and it works a treat - Dave C

I was quoted £145 for a buzzer for a 3GM. I used a 12v buzzer from Maplins but it's a bit too quiet so thinking again.

£145 - you've got to be joking! Mind you, A french Yanmar dealer tried toi charge me £600 for a new starter motor. Got one couriered from the UK for £150

Lucas do one that is a couple of quid more than Maplins, but is louder.

Don't know who your local suppliers would be but as others have said, low cost alternatives are quite suitable. Any 12 V electronic buzzer will only consume 20 or 30 mA so wiring shouldn't be a problem. When you look at a catalogue check out the decibel output for the amps consumed. You could even get a kit that supplies a destroyer type WHOOP to get more attention.

I quite fancy changing mine to bells, less pain when you shut down.

Thanks for the input. I pulled the buzzer from the dash and it has four leads: one positive and three to oil pressure, engine temperature, and charge. Any ideas how to deal with this?
Thanks!

The three sensors on the engine are effectively on/off switches connected to the wires you found on one side and to the engine block and hence earth on the other side..

There is 12v positive on the single wire of the buzzer. Each of the three leads from the buzzer goes to one of the sensors. Which ever sensor switches over completes the circuit and fires the buzzer.

And somewhere in there, arent there warning lights as well? If so they likely will be in parallel with the buzzer.

All from memory - get a digi meter and check it out but I'm pretty sure thats what happens.

Closer investigation showed four wires going to the buzzer: three from water, oil, and charge and one positive for power.
Even closer investigation, using a small screwdriver to pry it open, (what the heck ... it's not working anyway) revealed one wire of three had come loose from the buzzer diaphram. A wee bit of solder and some SikaFlex 291 and she's buzzing like a good thing again! /forums/images/graemlins/smile.gif
