Hello again Peter -

Thank you for your reply and info..

Ok - assuming that the battery is indeed ok - then you must have a parasitic drain causing this..

Such can be hard to find to be perfectly honest with you - It usually is a sticking relay... a faulty "computer" - module...and so on.. It can then even be something simple such as a boot light staying on ( unbeknown to you ) because of a faulty switch etc..

What we suggest in these circumstances is to go down the easy route first - so remove the bulb from the boot ( and glove box if fitted ) and see if the drain goes off... if it does- you have a faulty circuit switch on whichever is causing it of the two.

If its not that - then unplug the alternator fully- as that if it has faulty diodes will cause this - and re check.

If its not that - then you are now into possible relays / computers - and even the radio system as a suspect. The latter is quite common.. but at this stage, you are going to need to go down the proper route to find such a drain and that is to use an amp meter in the battery circuit - and then remove each fuse, one at a time - while checking the meter to see which one causes the drain to die away - at which point - you have your faulty circuit... then you need to ID whats on that given circuit - and then isolate the individual equipments to find the exact cause of the fault...

So thats the way forward on this Peter... Im sorry there is not a "it will be this or that " answer to this one - I have gone through it in the easiest way first for you -- thats the way to work through it to get this sorted for you now....

Let me know if you need anything else at all -

Kind Rgds - MIKE.
