Ford explorere 2008 battery drain

Hello,

I have a ford explorer 2008, I suspect that the radio is draining the battery while the car is off and locked. Using multimeter (connected in series between battery and car terminals) I got these numbers
power usage with radio fuse in: 400 milliamps
power usage with radio fuse removed: 40 milliamps
I took out the radio and removed the cover and then connected it to its cables again, one integrate stays very hot even if radio is off and the car is off and key is removed, can somebody please help, how much should the radio consume while it is off? if something is wrong with the radio can it be fixed? Thanks in advance.

Haven't a clue how much it should draw , but why dont you leave it disconnected and see if it cures your problem ? Are you sure your battery itself is up to scratch ? no weak cells ? Could get it load tested if any doubt .

Re: Ford explorere 2008 battery drain

400 mA seems a little high, that's almost a half an amp, but after looking at all that ties into the system, it really doesn't surprise me. However, it's supposed to monitoring the drain to prevent killing the battery. I'd get the battery tested first. I know on some of the later vans they had a problem with the delay module draining and killing batteries.

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?
