Isn't it fun?

Clearly something is up with the wiring as none of the guages moved.  The oil pressure never increased above about 0.5 bar, the tempoerature (Which was showing 80 degrees before I even turned it over) never moved from 80, the fuel tank never even got about an inch below empty ....  Oh, and yeah the car doesn't idle either, needed to keep foot on the gas to keep her running ... all points sent off to Derek, as I'm sure I must have missed something very simple.

Do you want suggestions now, or to wait till you hear back?

Do you have a multimeter? :-)

Good to hear its running Smile

On my Sigma car, the idle issue was just the butterfly closing completely, there is a very small allen screw on the Caterham throttle body to adjust this.

Definitely want suggestions ... !

I don't have a multimeter, but logic tells me the only one not getting any current is likely to be the petrol guage.  As the others do actually move.

I'll look at adjusting the throttle for the idle issue - thanks for the tip.

The fuel guage takes an age to move off the stop and with low fuel it may be working OK.  With the water temp guage, does it go to 80 straight after the immobiliser flicks off, or do you get the 80 reading when the engine fires? Does the oil pressure guage show any movement at all if you blip the throttle gently?

  1. What Jim says, and what does the rev counter do?
  2. I'd check all the other electrical functions...
  3. ... and that the layout of fuses and relays matches what's in the Assembly Guide or Handbook.

Recommended multimeter: Draper 60792.

and treat yourself to a pair of matching leads with croc clips.

The rev counter is ok.  IT's quite jumpy, not as smooth as a production car, but does work.

The water temp goes to 80 as soon as soon as it has power - i.e before the engine starts.

The pressure guage moved from the red to 0.8b or so when I was cranking with the inertia switch off.  However, once I started it, it didn't move.  Blips on the throttle does nothing.

How about the instrument lights (and all of the other electrical functions: lights, horn, engine fan, heater fan etc)?

The rev counter is ok.  IT's quite jumpy, not as smooth as a production car, but does work.

Jumpy when the engine speed is constant, or only when it changes?

With more than one instrument not working properly I'd check:

  1. That the system voltage is constant and appropriate, but that will have to wait for the multimeter.
  2. That there isn't a bad contact in the feed: check the fuse and its fit in the fuseholder.
  3. That the instrument earth is good: find it, see if it's loose, disconnect, inspect and reconnect.

After that it's on to tracing each suspicious circuit.

And the engine oil level again.

Re visit all the earthing points and give them a clean and tighten include under the scuttle
