Hello,

I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you,

all interior lights are off including the glove box light & boot lights, the security system will be taking power but I would expect it to be considerably lower. this load of 0.4A is approximately equivalent to a 5W bulb which would completely drain a brand new 100AH battery in 10 days. The current drops to 0.09A when I pull the fuse for the 'Body Control module'. What other info do you require?

Hello, welcome. My name isXXXXX will do my very best to
assist you with your question.

The reading with everything off and the battery sitting stationary should be between 0.8 and 10.0 amps. With the reading at 0.4 the battery likely has a dead cell.

Are you sure about this, the battery wont last long with a 10 amp draw off whilst parked up?

Expert:  Mike Kelly replied 3 years ago.
It's closer to 8 but can be 10.
