Hi,
Thanks for speedy reply. Only problem is that I am in France and now that we are post-brexit can we still send items for repair without either long delays or costs?
I`m going to put battery on charge for rest of day/night just to confirm that it is not an alternator problem. I have had "low battery" light on and off for about 10 days so charging will cost nothing and might point in other directions. I`ll keep you updated.
Chris.

Hi,
Just checked battery and around 12.5 when engine not running and 16 once engine running so unlikely to be alternator.
Tried resetting ECU by pressing start/stop button 3 times and then restarted car. hey presto no warning lights. However having decided to take it out for drive, lights back on after about 200 yards.
Methinks it`s time for garage or at least someone more knwledgable about Mondeo cars.

Methinks your alternator is overcharging at 16v but feel free to find someone more knowledgeable .

Agree 16v is high but why would it suddenly give out 16v and would that affect all the system?

Why does any electrical device give out ?

Yes

Re first comment. I`m surprised that the alternator could supply higher voltage. Lower voltage yes because dodgy windings possible, resistance in circuit, poor connection. But, how would it increase? Or am I being too simplistic which the car obviously isn`t.

I'm afraid my teaching days are long gone and I have no desire to start now . Suffice to say it's only a Mondeo and nothing sophisticated like some makes and like all cars , overcharging alternators are not a rarity . Such conditions can " fry " your battery so you may need to get it load tested also . Just to add , your car has a smart charging system and it is imperative when you replaced battery it was a Silver Calcium and not a lead acid battery . But that's only my opinion .

No idea whether it was a Silver Calcium as bought it while on holiday in Spain.

If original was Silver Calcium that might explain why the charge voltage is higher than you would expect.
Long way to go and ask garage what old one was and in any case will have gone to scrap a long time ago.
