CTEK question
Morning chaps
My battery was almost dead on my D4 yesterday,so I put the CTEK on overnight.Came out this morning and for some reason it's not charged ...

What mode should it be on ?

Normal
AGM
Recond

Ok, that could be a connection problem, a battery failure, charger fault or a very large current draw whilst charging.Land Rover - Turning Drivers into Mechanics Since 1948

I've been having a current draw ever since I had a load of accessories fitted..ie TV DVD reversing camera etc.Thats the reason I bought the CTEK so I can live with the problem,I did talk to my dealers but it was going to cost a small fortune to get diagnosed ...so I left it.

Your current draw could be confusing the Ctek or perhaps the draw has taken its toll on the battery.
Need to know the voltage of the battery as it is and then you need to disconnect it from the vehicle and charge it properly. From there you need to understand what current is being drained when parked.

If all is well then charging on the vehicle is fine. Clearly you have issues so the drain of the car needs to be taken out of the equation. The recondition mode of the charger should not be used with the battery connected to the vehicle either.

If you still can't find the manual I have a couple of Ctek manuals in PDF format, so I might be able to upload it for you.
