battery drain...
2004 expedition xlt
My battery keeps going dead, trying to figure it out...
When testing the fuses in the junction box in the kick panel with a voltmeter, are they all supposed to register volts even when the car is off, doors are shut, and everything is supposed to be shut down?
Because they all are, even the 4x4 fuse#20

Yea, I thought it might be because I kept hearing an intermittent clicking coming from the back windshield wiper area,was too late last night, will confirm tonight.
I really hope it wasn't due to my "battery incident" lmao

If it's not the wiper you can narrow down the source of the draw using an amp meter. Start by disconnecting the negative battery cable and then connect one meter lead to the negative cable and the other to the negative post on the battery. Record the reading, then reconnect the battery.
Now in the fuse box pull fuses one at a time and touch the meter leads to the 2 fuse terminals in the fuse box from where you just pulled the fuse. Record the reading, replace the fuse, then move on to the next fuse and repeat the process for the other fuses. Once the readings from the fuses total up to the draw recorded at the battery cable you can stop. Start with the circuit where the biggest amp draw occurred because that's likely where the problem is.

Thanks for the great suggestion alloro! Here is a pic of the voltmeter I have, it has amp settings, is this sufficient enough? and if so what setting do I need to put it on?

Start with the 10A (7:00 position) setting in case the draw is more than 1/5 of an amp (200 ma) which is the next lowest setting. Black lead into the COM and the red lead into the 10A. Start with the fuse for the wiper, as it is usually the culprit like
