As above, when i turn the bikes ignition to on, the tempreture immediately jumps past hot on the needle, it maxes out, none of my instrument lights are working (neutral, turn, etc....), however main head light works fine. Not messed about with any of the wires at all?

Any ideas? I've checked fuses, all ok

Sounds like a short somewhere. Could have rubbed through the plastic covering or melted on the rad etc.

Main earth fixing on reg. unit (23) or seat bracket (NC29) is what I would check first ......
