sailor beyond_theft just bumped this 8/24/14 with "I've got the same problem" post.

Always messes up the reading when that happens...

kanarrjl You do realize that the guy that you were replying to posted that in 2013 right?

I do not know much about drain tests, but it read 20.67A.
Because he said he has a "power drain". I assume that reading is with the vehicle off... as that seems pretty darn normal if the vehicle is running. But at the same time, he must have his decimal place in the wrong place.... as a 20A parasitic draw would kill a battery in an hour easily.

kanarrjl Here is a good video of the draw test. What is the reason that you are suggesting the test though?
10-06-2014 09:55 PM
firebirdude Use a multimeter and google how to do a parasitic draw test. Pull fuses one by one until your drain stops. Then you've isolated the problem to one small circuit. Should be pretty obvious from there.

Focus Fixer Too I have a 2001 Focus wagon, and frequently the radio just goes dead! Then sometime later it come back on again. How do I get the radio out of the instrument panel? I think the post above about a new ground wire might be the answer, but I don't know how to get at the radio....
08-25-2014 01:10 PM
freemind Run a new grounding wire 12-14ga from the deck straight to the drivers side kick panel behind the plastic trim. Drill a hole in the flat metal, use some sandpaper to sand the spot to bare metal, then use a star washer, a ring terminal and a metal screw to attach it with. Cover with dielectric grease and you will have a solid ground.

Post results.

mtbrider730 after getting a test at advanced auto, there was an alternator problem. I replaced the alternator and got it retested. The new alternator is perfect but appearently there is a power drain.

I do not know much about drain tests, but it read 20.67A. I figured I would start with checking grounds.

Does anyone know where the ground for the radio actually goes to on the car?

mtbrider730 Replaced the alternator after getting it tested at Advanced. When I reconnected the battery I noticed it was corroded, so much that the car was actually having electrical problems (wouldn't start and lights were dim). I have cleaned the terminals. I also but a new tensioner on the serpentine belt but still having problems with the radio. I have been getting shocked a lot by the door jam getting out of the car. Given it is winter and you tend to get shocked more in the dry air, but could it possibly be a ground?

Any help is appreciated!
