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.
I've purchased a 1999 S1 Exige Motorsport which has a Honda K20A and Jackson Supercharger installed. During the winter months i'm tidying up the fuel & wiring installation ready for 2013 or to sell on once tidy. I've renewed all the fuel pipes and now it is time for the electics to be overhalled.
The base Exige S1 has four separate relays in the engine bay rather than the MFRU box found in my S2. I purchased manuals for Elise S1 off eBay but non of the wiring diagrams have separate relays for start relays, fuel pump, main relay and O2 sensor (Possibly). Does anyone have wiring diagram / colour codes for elise with separate relays? I am usure why it has separate relays?
I need to re-wire swirl pot and additional fuel pumps as they are poorly wired. Currenty they have a separate relay and wires energised from the ignition and are on constantly when you turn the ignition to position 2 (Prior to cranking engine)
1) Does anyone have a wiring diagram/harness colour codes for Elise with 4 separage engine relays?
2) Will it be possible to wire fuel pumps to just prime and presurise fuel rail or will they need to be running all time from position 2 of ignition? Currently the inertial switch & cobra immobliser are not in the circuit and ideally i want to get these wired in so in the event of a bump fuel is cut off.
I have tried to map the wiring harness colours for the two Engine Harness Connectors but they don't seem to match what colours are detailed in the Lotus Service Notes.
Any help would be appreciated.
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.

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?
