XJ12 Series 3

[Steveinfrance]

Hi guys,

Here I am in rural France with a sick XJ12HE dumped on me, and amongst all my books I cannot find a wiring diagram that suits the last of the HE series.

I am having trouble sorting out the ignition circuit as it has been well bodged with all sorts of colours and connectors.

It would be really helpful if someone could post on here or email me with at least the ignition circuit including the list of wire colours.

Thanks in advance;

Steve

I believe it is a Lucas Opus ignition system and there used to be instructional manuals from Jaguar on the system which may still be available on eBay

I could be wrong but i'm fairly sure you're right about the early V12s being Lucas/Opus electronic but something in the back of my mind says they changed to a Hall Effect trigger in the dizzy when the Lucas (copy of Bosch L-Jetronic) EFi was fitted.

I'll try and find some old diagrams that may show it but don't hold your breath.......
