I have a slight voltage draw that is slowly draining dead the battery on the 89 5.0. over 3-6 days.
I disconnect the positive and put a DVM in series between the pos terminal of the batt and the pos cable and see no mA draw, I do see about a 1.5v dc draw, that slowly settles to around .5v over a couple minutes. IF I open a door, it goes to 0volts, soon as the door is closed, it goes back to .5 or so...
I was thinking alarm sys, but since the fuses are well up in the dash, I was being lazy and not pulling them yet. However, it is not armed at the time of the test.
Am I even doing this test correctly?
Any other ways to look the system over?
Thanks!!!!!!!
