Re: Parasitic current draw
New poster but I may be able to help. Disconnect the negative battery terminal. Connect one end of the test light to the cable and the other end to the battery. Close all the doors and make sure the truck is off. If the test light lights up you have a draw. Start removing fuses until the light goes out. That is the circuit that is causing the draw.
You will have a draw from the clock in the radio but it usually is not enough to light up the test light. If you have a multimeter hook it up the same way and look at the amp draw. Anything above 500 ma will drain the battery and is not normal.
Hope that helps,
Sean
