Pendennis Posted March 2, 2017 Share Posted March 2, 2017 Good evening, struggling to quickly work this out so does anyone know where the ignition live, earth and sender wire connects to on the back of the gauge terminals 1, 2 & 3? Link to comment Share on other sites More sharing options...
Pendennis Posted March 2, 2017 Author Share Posted March 2, 2017 I think sender is 1, ignition is 2 and earth is 3. Could anyone confirm please Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 2, 2017 Member Share Posted March 2, 2017 I don't know, and the terminals aren't identified that way on the factory wiring diagrams that I have with me.This discussion agrees with you. (Ignore the recalibration gadget.)JonathanPS: Would you like the diagrams? Link to comment Share on other sites More sharing options...
Pendennis Posted March 2, 2017 Author Share Posted March 2, 2017 Blimey Jonathan, where did you find that.I have a wiring diagram but as that old PH discussion mentions, the diagram doesn't label terminals on gauge. I was pretty sure how it should be wired but wanted confirmation. Cheers for that your a star Link to comment Share on other sites More sharing options...
John Vine Posted March 3, 2017 Share Posted March 3, 2017 Ah, I think I might have the answer, having just removed my gauge to recalibrate it:Looking at the back of the gauge, with the lamp tube uppermost: RH terminal is 12v supply (green wire) LH terminal is sender input (green/black wire) Middle terminal is earth (two black wires on my car)On mine, these wires are held in a three-way plastic connector (unlike the PH photo that JK cites).JV Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 3, 2017 Member Share Posted March 3, 2017 The current Caterham diagrams show the connection pattern on connectors, as described by John. But not the terminal numbers. Jonathan Link to comment Share on other sites More sharing options...

John Vine Posted March 3, 2017 Share Posted March 3, 2017 At least the wiring diagram in my Assembly Guide matches what I have on the car!JV Link to comment Share on other sites More sharing options...
