why is my battery draining overnight. i have got a silver top bosch battery and a uprated alternator which seem to be ok.when i go to start it in the morning the battery is flat to start the car,when you put the jump leads on it starts straight away and you can dive away no problem.is it a good idea to take the earth leads off the batterey overnight and then see what happens in the morning to give you some idea of what wires draining it.
any would be much appreciated
cheers
