Thank you, I've saved that site to my favourites For the moment, I think the XJ is a runner except for the CDI and coil, it's the CDI that's proving most difficult to find so far. I've e-mailed loads of breakers so I'm hopefull. I've got the impression that this CDI was only used for 90/91 models, which makes them a bit rare.
Does anyone have any suggestions as to why they died? It coincided with poping most of the light bulbs and fuses and a very dry battery. When I bought it, the guy said he'd had a new battery recently, but I didn't think to check it immediately. A week later and I'm off the road. It is just possible that he fitted it dry, but we'll never know. The other possible, is that it may have boiled dry, and that's quite worrying, because that'll mean I haven't found the cause yet. Any suggestions are worth checking out.
