Electrical Draw?

[powerstrokin99]

I have had an issue where if I dont drive my truck for a couple days, the voltage on the batteries goes way down and it wont start up. I have done the volt meter in the battery series check and pulled all of the fuses one by one. Then I disconnected the altenator just to make sure it wasnt that. The draw never went away. It shows a 4.2 amp draw on it. Any suggestions would be great, ITS COLD OUT THERE

You don't have an aftermarket stereo do you? You don't buy any chance have a problem with the door ajar deal do you? What about a brake controller, mine has a constant draw but isn't supposed to kill the batteries for six months, maybe it is malfunctioning. Make sure you have everything out of cell phone charger and cigarette lighter. I was told by a battery shop technician that with the temperatures we have been getting a cell phone charger could drain you batteries over night even if you don't have your phone hooked up to it.
