Cheers to you both, will try shorting it tomorrow and if the warning disappears will get a new float.

however despite the coolant level being perfect and the level is now holding steady I am still getting a Low coolant warning on the dash. I will keep an eye on it but it appears to be fine although I have got a slight sporadic dip in the revs when idle.
Check the crimping of the large leads entering the battery terminals too. These get loose causing poor charging and the resistance also causes starting issues. The dead give-away is that they start to get warm.
There should be a grounding strap from the engine to the chassis and up to the battery negative terminal. It connects just under the air conditioning compressor. Check this is sound.
Try connecting a jump lead from another vehicle, negative to the lifting eye on the engine and positive to the battery + terminal. This will eliminate the battery and possibly the grounding strap.
Try connecting the smaller solenoid terminal on the starter directly to the battery +ve terminal WITH THE TRANSMISSION IN "N"! See if it turns over then. If that works, you have high resistance in the ignition switch or gearbox selector at a guess.
Starter motors are normally super reliable on the V6, so makes sense to check everything else thoroughly.
