I've two points worthy of mention Firstly, I've had an ignition switch fail and the car wouldn't start. When turning it the red charging warning light didn't come on ie no power to any ignition switched circuits. This should be easy to test for, with a multimeter and wiring diagram. I fitted a replacement land rover switch (from Rimmer Bros) into the existing lock barrel thus keeping the original key. Secondly, the K series 'click' is a known fault where one of the relays within the Multi Functional Relay Unit (MFRU) fails. Googling these terms should yield some solutions. Reading your description I'd start with the second suggestion. Ian
