You are going to have to pinpoint what is drawing the battery down. Disconnect the negative battery terminal. Put a test light between the negative cable and the negative battery terminal. With the key out of the ignition switch and the vehicle just sitting there (make sure the doors are closed) the test light should not light up bright. If it does, there is a draw! Disconnect one fuse at a time until the test light goes out. When it does, u have found the circuit that the draw is on! Here is a hint, a lot of times it is either the dome light, trunk light or the glove compartment light that stays on. If you do not want to go through the hassle of the test, pull the bulbs out and see if that helps.
Ok... Can you tell me which 50 amp fuse you are talking about?
out of the 3 x 50 Amps, the nr. 3,7 and 15 it are the number 3 and 7 both. When you pull 1 the draw is reduced by 50% if you pull the other the the draw is gone...
I believe this is the circuit that you are talking about. Everything that is on fuse number 3 should be on here.
This should be it.
Let me come back on that. I did find out that in case I turn of the interior lights (by turning the knob of the dash illumination completely off) and then closing or opening the door it takes about 8-10 sec. and the draw is gone. So it must be in the Interior/Dashboard related. I did not see any lights burning, but 1 by 1 I will pull them all.
Ok... Sound good!
Let me know!
It could be a module that is causing the draw. This is actually normal. It is supposed to pull a small draw for about 30 minutes or so until after the key is turned off. HOwever, if the draw continues, then we have a problem. Check how many amps or milliamp is being pulled from the battery after about an hour or so after the key is turned off. THis is going to be the most accurate test.
Let me know what you find!
I did measure the Amps today.Started out at 0.7 amps. Then by turning the dashboard light dimmer all the way down it stays at 0.7 amps for 10 sec. then it goes down to 0.25 amps then after another 10 sec. it goes down to 0.18 amps, I assume that about 2 watts of a draw is normal? Still do not understand why the draw is reacting on the dashboard light dimmer switch even with no lights or interior bulbs present.
Other thing I noticed, which I do not know if that is normal, but each time I switched the power on and off (disconnecting the battery) the lock of the tailgate door switches. I think that uses power all the time is that normal?
