Apothecary Posted October 23, 2005 Share Posted October 23, 2005 I had some long awaited DVA attention to my Superlight this weekend 😬 (thanks again Dave ) I now have an Emerald grafted onto the EU3 loom (that was fun ☹️) An unanticipated side effect is that the single (top) LED on my Tacho now stays permanently illuminated. I dont need the Emerald to run a shift light (which is what I thinik this LED is ?) as I have ACES fitted and want to keep them. Does anyone know how I can disable this tacho light ? Is it a matter of identifying the correct cable from the back of the tacho and cutting ? If so which one is it and will it only disable the light and nothing else?

Myles Posted October 23, 2005 Share Posted October 23, 2005 You could try setting the shift point above (or at) your max revs (I *assume* you have access to a laptop etc...???) Alternatively, cut the wire... I'm sure I've read about this in the archives - try a search over the last couple of years. Project Scope-Creep is live...

Myles Posted October 23, 2005 Share Posted October 23, 2005 here for instance. Looks like the shiftlight wires were swapped over between EU2 and EU3... Project Scope-Creep is live...

martinwhitcher Posted October 23, 2005 Share Posted October 23, 2005 Relay needed by memory, My eu3 engine was exactly the same, traced it to needing a permenent earth instead of a live, one or the other.

Rob Walker Posted October 24, 2005 Share Posted October 24, 2005 Simple cut one of the two wires that supply the LED. Link to comment Share on other sites More sharing options...
Apothecary Posted October 24, 2005 Author Share Posted October 24, 2005 This is helpful, thanks Guys. Rob, I am tempted to do just as you suggest. Which wires supply the LED? Paul SL No.174 Member No.109xx Pictures here Link to comment Share on other sites More sharing options...
Rob Walker Posted October 24, 2005 Share Posted October 24, 2005 The two wires that connect to the back of the LED. Just pull the LED out from the dash and disconnect one wire and tape up the live end. Link to comment Share on other sites More sharing options...
Myles Posted October 24, 2005 Share Posted October 24, 2005 Rob - the LED in question is embedded in the tacho - so he needs to know which wire in the tacho plug to vape....

Apothecary Posted October 24, 2005 Author Share Posted October 24, 2005 Myles is right the LED is inside the tacho so I'm not sure which wire feeds this light only. My get around so far is to remove the tacho from the dash and after unpluging, remove the gromet from the back to expose the two DIN switches. Switching the first switch off (down) has turned the offending LED off. An unwanted consequence is that now when I use the indicators the small central LED (green) at the bottom of the tacho only lights if I indicate left. Indicating right there is no illumination . The other small LEDs all function (red - ignition (RHS) and blue -full beam (LHS). I can live with that but would prefer to have the indicator light back to normal if anyone knows a better solution.

Myles Posted October 24, 2005 Share Posted October 24, 2005 I'm sure there is reference to the wires deep in techtalk - many people over the years have asked how to wire it up for non-SS cars... I'm not convinced of its worth though - I've got the full-on ACES system - on top of the scuttle - and that doesn't get my attention anymore... Project Scope-Creep is live...
