I have a horrible feeling it may be the battery as suggested by someone here.
I noticed that the ignition lights dimmed when the gearbox was put into reverse , I suppose that the battery would read twelve volts when it came off a quick charge because that was what was in there , it just had no amp hours.
If it is I will buy a kill switch ,but not like the key one I had on a Series 3 which caught fire.
It is still on charge and will try tomorrow.
The starter relay is indeed by the washer bottle ,the relay that is clicking is behind the steering column ,it is not the flasher relay as I found that , it is either a relay from the starter inhibitor from the autobox or more likely from the brake check circuit.
