Elise "stack" Dashboard Problems

5 posts in this topic

Hi everyone,

 

this is driving me mad over the last year. On my s1 elise I have a electrical problem....

 

After I have turned off the engine and removed the keys the stack dash lights stay on, they also flash brigh/dim, the revs and speedometer also light up along with the the digital screen, the lights come on intermitenly and are causing the battery to go flat.... Other than that the car run's great and everything works as normal (including the Dash) when the car is started....

 

This was original posted without any soluition:(

Has anyone got a cure for this !!! Help would be much appreciated.

 

thanks :)

I dont unfortunatly have an S1 wiring diagram any longer. However you obviously still have a feed to the Stack unit with the keys removed ( possible short circuit ) You need a wiring diagram and start at the stack and work back from there. Also S1,s sometimes have a shorting problem with the front relay / fuse box.

 

IIRC they are attached to the top of one of the front wheel arch liners ( n/s ? ) Remove the fixing pins and turn them over and check for water / corrosion caused by water.

HI,

thanks for the reply, I've got the S1 Wiring diagrams...eeekkk. But I'll have a look later tonight and at the Fulse & relay box. what is the IIRC - is it the RELAY box?

 

thanks

Hi, thanks for your help so far, That OK about the IIRC's. OK, I've done a bit of work:

 

removed dash/Stacks -all looks OK. I tried a ddirect earth from inside of the stacks to the Chassis - no luck

Removed all Fuses - all looks OK, the only fuse that stops the problem is to remove the 7.5A "stop lamps & battery services".

Removed all the relays and everything looks excellent - removing the relays didn't stop the problem.

Disconnected ECU - no joy

Disconnected other little black box in the boot beside ECU - no joy....

 

.....grrrrrrrrrrrrrrrrrrrrrr...

So I looked at the problem on the STACKs in a little more detail. Only the Oil Pressure & Seatbelt light are comming on when the ignition is turned off/key removed. If you insert the seatbelt this stops that light going on/off, therefore only the Oil Pressure light & alarm light come on. Further investigated this...Car Runs perfectly, When you turn off ignintion and remove keys all dash lights go out after a couple of seconds, after another couple of seconds the ECU has a CLICK (like a circuit/relay is connnecting) [ this click noise comes from the ECU]. Straight after the click the Oil Pressure and Seatbelt light shows and alarm light comes on like normal. If you plug-in and then remove the seatbelt the light goes on/off etc..

 

I do have a wiring diagram - but lost where to start now.

any help would be much appreciated...

 

thanks

      I have a challenge with the readout of the temperature and I could use some advice.

       

      Warm engine gives a readout of 87 C, lights on then 92 C, heater on then 98 C and then radio will then also start engine fan, as it get over 100 C in the display.

       

      Good ideas? Experience?

       

      Regards

      Hi All,
       
      Thought I'd stick up a quick note to introduce myself - I have just bought Jon's lovely yellow S1 Elise!
       
      The car is immaculate and an absolute credit to Jon's care and attention to the little details in ownership. I will endeavour to keep it in the manner unto which it has become accustomed!
       
      I am based in South Manchester but the car will spend most of it's time in North Wales so I'll keep an eye out on here for Welsh runs and see if we can get along.  I'm also hoping to get across to the Chatsworth event so would be good to meet some fellow owners there.
       
      Cheers
       
      Chris

      As a newbie to the MLOC forums, I will take the usual stance of asking a stupid/dificult/irritating question and expect everyone to instantly drop everything and help
       
      But seriously... Having just bought my first Lotus (a little S1 elise) I'm really looking forward to being a part of the Lotus community and meeting a few of you all at track days. But before I can do that I need to fix a couple of small problems on my new track mule.
       
      First up is the Stack. I'm assuming the sticky/sluggish speedo and rpm needles is fairly common. I'm putting it down to lack of use (27k miles in 15 years) and expect them to free up. More urgent is the lack of illumination. All the warning lights work, but there is no illumination when the side or main beam headlight button is engaged. On the plus side, the headlight buttons do light up correctly, so I would hope it's just a bulb gone in the stack itself.
       
      If anyone has a wiring diagram of the stack unit or has been round this loop before, a bit of learning prior to pulling the unit out would be most welcome.

      Lello Ladies and gents,
       
      I have a 'Stack' 'Monza' IP from either a S1 or S2 Elise and I would dearly like some help - Apologies for the following.. I would love to graft the beautiful Lotus IP into my kit car. [it is NOT my intention to offend anyone here].
       
      I have 2 areas to consider:
       
      1. How can I get the indicator light on the IP to work? (feeds / Pins required?)
      2. Which (Lotus) sensors will I need to get the correct readings for the Lotus IP to work? (Not including Engine management)
       
      Lotus have basically said that they do not wish to help (and why should they) and Stack have referred me to Lotus.
       
      Below are my findings so far - the IP looks just beautiful when powered up ... but alas, it is on my work-bench! I have looked and looked over the internet and I just can't find the detail I am looking for.

      I hope that the above does not cause offense to anyone - the findings above are my personal (Laymen-esque) thoughts.. please do not take them as gospel (and blow up your own IP's).
       
      If someone has any suggestions (constructive please!) then they will be gratefully received. (yes, I will have an Elise one day.. but until then, the kit car is my little toy)
       
      Thanks and regards,
      Roy

      Went out in the car yesterday; battery didn't have enough charge to start it - cue lots of clicking.
       
      Jump leads and starter battery later and she's fired up and burbling away in the garage.
       
      I set off to find that the rev counter, speedo and LCD not working; the seatbelt light that usually goes off after a few seconds is lit constantly.
       
      Turn the ignition off; back on - all usual lights work but the speedo, rev counter and LCD are still non-functional and the seatbelt light remains lit again.
       
      I take it out and use my sat nav as a speedo whilst I get to my meeting; after the meeting all is the same.
       
      This happened once before and after a few minutes of the key being out my mileage switched to kilometres but everything else went back to normal working order it would seem.
       
      This time it's having none of anything.
       
      Is there any connections or fuse that could cause this or is it fucked?
       
      Got a tour of Lotus next month so will have to get it fixed or rely on OBDII port for functions until its sorted.
       
      Chap on SELOC had a similar issue and thought it was an earthing problem - anyone know what I should be looking at?
