Parasitic Draw

[AlecV]

There is a battery drain in my 1997 Expedition XLT, as noted in my older post. The drain is 5.46A. I am receiving a DVD manual from a great member soon, but until then, anyone have any ideas? Is it possible that my JVC Radio is draining it? Also, there is a cord above it fitted into the open space that was left over after stock radio was removed, since that thing was giant. But it is simply a cord that a USB fits into, I am being told that it is part of the Bluetooth system..But I don't see why that would be. I honestly don't think it's part of the stereo kit. Could a cord like that possibly drain 5.46A?http://www.usbgear.com/images/USB3-Extension-6FT.jpg
The left port is one that is fit above radio...I assume it was put there to charge things, by plugging a USB into it.

In the electrical section I've posted a sticky that links to a video on how to find the draw. Usual culprits are lights staying on, gem issues and a bad alternator staying energized.

I clamped a multimeter to battery and disconnected fuses one by one, both in the engine compartment, and in driver's side. Not even a single drop in A after doing so.

with the truck cold and the battery charged is the alternator warm to the touch?

When dealing with electricity it is better to think logically.
Logic would state that:
1) It is on another circuit that you haven't pull a fuse on or
2) There is an additional circuit that has been added or
3) Alternator has a draw - disconnect the plugs on it, leave the wire with the eyelet on (+12v).
4) You missed a fuse (I've done it...)

Nothing from the factory is unprotected: either fuses or fusible links were used during production.

I'll go over them again tomorrow. I will also check about the alternator. Thanks for info, I'll keep ya posted.

What is the amp draw at the present time?

 

[stamp11127]

He hasn't stated any changes have been made so I would expect it is still 5.46 amps. A pretty good draw.

 

[Bedrck47]

ok wasn't sure if that was the total draw

I would expect the alternator, a light is stuck on or the GEM is getting a signal to keep a circuit energized will be the cause.
