You could stare at the wiring diagram all day and not figure this one out. I'm hoping someone with more knowledge than me of where the wiring loom traces will have an idea on this one.
On #2727 we're having a really bizarre problem. The ignition relay will not turn off when the key is removed. If you un-plug the switched feed to the relay, it of course turns the relay off, but plugging it back in does not turn it back on. From this I assume the relay must be powering itself somehow (turn it on and the supply it's switching is somehow fed back to the coil).
In thinking about this, when in the "powering itself" condition, we removed each fuse in turn thinking that whatever system that was fed from the ignition relay that was also powering the ignition relay would be turned off by removing the fuse. Well it was a good place to start!! Anyway, removing fuse #4 (Brake + DI Lights) immediately turned the relay off, and with it removed the ignition comes on and turns off fine with the key. Bizzarrely though, the brake and indicator lights STLL WORK without this fuse in place.
You know how turning the igntion on often results in the RPM relay cycling once and turning the fuel pump on for a second or so? Well, #2727 does NOT do this. However, with the ignition on, of you turn the headlights on, or flash the high-beams with the stalk, the RPM relay cycles.
Oh well it's Rich's car, and he's at least as capable as me on electrical things, so I'll just take a back seat and revel in the fact that #1458 works beautifully, even if I can't work out how the damn glovebox goes back together.....
