Oil warning buzzer?

Right, fitted some VDO gauges and they work a treat. But here's the problem, if i rev it over 2000 revs the oil warning led starts to flash and buzz constantly. If I don't rev it over 2000 revs it's fine. I disconected the wire off the new oil pressure sender for the warning led and it had no effect, same problem. Also I noticed that there was a wire that was not connected to anything, right next to the wire for the oil pressure warning LED. It is a green colour? :dontknow:

Sorry for blurry images, hope you guys can help.
Old oil pressure sender, you can just see the wire that isn't connect to anything.

New sender with unknown wire?

Few pointers for you , oil wires are yellow for low pressure and blue black high pressure . The high one is mounted on the filter head low on cylinder head . I fitted guages to my 20VT conversion so did not want the oil light or any MFA function etc on the dash except the digital clock , so did not connect the oil wires to the clocks and guess what buzzer and flashing oil light over 2000 rpm . Driving me mad .

This leads me to think that if the clocks are not getting the right signal they will buzz . So fitted the oil wires to the clocks and earthed the buggers under the dash , problem solved    :mrgreen: You could of course remove the buzzer and lamp if you wanted , but thats more work and may affect clock functions ?  

So if you are happy to have 'NO' clock oil light simply earth both wires near the clocks and use separate guages . If you need MFA oil temp ? That should be fine as its the green black wire and not connected to the buzzer .

Essay ! hope it works ?

Cheers …….

i had the same problem i used the vdo gauges instead of my dash ones everytime i got over 2000rpm the buzzer would go mad so i found the wire and earthed it out this shuts up the buzzer :wink:

Cheers boys, connected the lead to the battery and sorted. This is exactly why this forum is soo good. Simple solution. :mrgreen:

If after carrying out the above the buzzer stills sounds the general opinion is that the clocks are faulty !
