Truck keeps dying

[Mr Hagg]

I find the best way to find a drain on a truck is with a thermal camera .. I look for hot spots. If you dont have access to that. Take off negative cable and I use a volt meter and put it inline from neg bat to neg cable. Then start unplugging stuff until it goes to nothing. With a good draw it will show 12v once its gets down to like 4 or so then that may be your truck normal... Check alternator as those tend to have regulators stick and cause it. You will know cause alternator will be warm after setting over night.
