My 2004 expedition is draining battery overnight
I do not know how to trace it and I am not too good with electrical problems

Any help would be appreciated as I am now taking off my neg battery cable every time I get out of the truck
Thanx in advance

Steve

 

Usually , we attach an amp meter in series with one of the battery cables after the engine is shut down and get a reading of how many amps/milliamps are being drawn from the battery while at rest. We try to keep the draw below 50 milliamps. If it's draining the battery it has to be over the 50 number. With the meter connected start removing fuses one at a time .When the reading drops a lot that would be the circuit to require further investigation. Don't know if you want to get into this any further so will stop here. If so let us know and we will try to help guide your moves.
There is a battery saver relay that is supposed to prevent this problem, but if your electrical desires are not that great it might be better to have someone with more equip check it out.

 

Thanx Hanky,
I will give it a try and I really appreciate it
