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?

this procedure resets the tach and speedo needles.


* Door open / key not in.


* Press and hold trip odo button on RHS of steering column.


* Insert key, turn until lights come on.


* Wait until needles reset a few secs later .

      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?

      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.

      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.

      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.
      Wire Col. Main/Stripe
      Connection Details
      12V Battery Feed
      Purple No Stripe
      Continous Battery Positive Feed Through Fuse (7.5A ?)
      Black (Heavy Wire)
      To Chassis or Battery Negative
      12V Ignition Feed
      Green No Stripe
      Ignition Switch Positive Feed Fused
      Tacho Input
      5V Out, Switch to Chassis Through Diode, 2 pulses per Rev
      Speedo Input
      Yellow No Stripe
      5V Out, Switch to Chassis Through Diode, 400 pulses per MPH
      Temp Gauge
      Resistance to Chassis, Short Cold, Open Hot
      Fuel Gauge
      Light Green/Black
      Resistance to Chassis, Short Empty, 150R = 21Litres
      Fuel Sender Voltage
      Feed to top of Fuel Sender? Not Used
      Main Beam Light
      12V Input to Light LED
      Battery Warning
      To Chassis Through Switch for LED On
      Brake Warning
      To Chassis Through Switch for LED On
      Oil Warning
      To Chassis Through Switch for LED On
      Engine Fault Light
      To Chassis Through Switch for LED On
      Panel Illumination
      To Chassis Through Switch for LEDs Off
      Tacho LED
      12V Input to Light LED
      Panel LED Adjust
      To Chassis to Set Brightness, Also Resets Trip Counter
      Rear Fog Light
      To Chassis Through Switch for LED Off
      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,
