Over Rev Warning Buzzer S3

[DKWW2000]

The Buzzer does not seem to work, I have taken Revs to 7000 but no sound.
I have checked the obvious things. I can not think of a logical reason why it would have been disconnected so I assume there must be a bad connection somewhere or Buzzer is Kaput?
I have been through the wiring diagram but to no avail
Has anyone had the same problem or could offer advice please

i have a set of S3 clocks if thats helps, can't confirm the buzzer works but sure i can test it

it may be faulty, or have been disconnected ( they get on some peoples nerves!) or maybe it's been adjusted to buzz at higher revs... I think there's a pot inside the tacho to adjust the buzzer limit.

Thanks for that offer, I might come back to you if I determine its the speedo,

I guess I will have to take out the speedo, thinking about it, is it the same buzzer as Low Coolant as I do not remember it sounding when the light came on the Dash.
If it was disconnected where would be the most likely point, any suggestions?

I think it's hard wired into the clocks so any disconnection would have to be on the back of the instrument cluster.

I was filling up my coolant the other day and my low coolant buzzer wasn't coming on. But my rev warning buzzer does work Seems to be the only noise/buzzer that goes off in my car

How easy is it to remove the clocks & Is it the same Buzzer for Low Coolant/Over Rev?

[ian65]

not too bad... the most difficult part is removing the 2 screws that go into the bottom of the instrument cluster... they need to be removed from underneath the dash, 1 either side of the steering column.
You then need to:

Disconnect the battery then......

1.Remove the steering wheel ( just undo the nut and keep wobbling the wheel until it comes off... under no circumstances must you strike the steering column with anything)
2. Remove the steering column surround
3. Remove the combination switch from the steering column
4. Remove the black plastic surround from in front of the instrument cluster
5. Undo the 2no remaining screws securing the instrument cluster... they are located at the top front.
6. Carefully ease the cluster forward and release the speedo cable from the rear of the cluster.
7 Pull it forward some more and undo the 2no multiplugs that power the cluster.

The instrument cluster is then free to come out.
The good news is that you can plug it back in and test your buzzer etc without fully re-installing it... just plug the multiplugs back in.

Sounds like a lot of work but should only take about 30 mins to remove it the first time you do it.

Many thanks, I am guessing now having studied the wiring diagrams again, it must be the Buzzer :x as it seems to be activated by the Low coolant switch as well.
