Shurlock Not Working

[the DustRoom]

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?

* Insert key, turn until lights come on.

 

* Wait until needles reset a few secs later .
