Ford TSB 05-22-9 Battery Drain Diagnosis---service tips TSB 05-22-9

Anyone have ideas of how to find this TSB? Thanks

They will have it at a Ford Service Dept. I took my 2005 in last Thursday. I gave the tech that number and he looked it up. They have a booklet of TSB's. He said this one was quite detailed. I will let you know the results when I get my car back.

Thanks, I believe that the answer to "battery drain" on these Birds is the regular use of Battery minders, maintainers, or tenders, i.e., for the long haul. The electronics draw on the battery probably is too much for a Bird that sits for more than a month or so.

The clock is the only constant "parasitic" draw I am aware of, although there may be some insisnificant small amt of current used to hold info in engine computer. It annoys me that the map light stays on so long when the car is switched off. However, all modern vehicles have the same situations. I have an 02 and my wife has an 03 tbird and we never have a battery problem, and our cars sometimes sit 2-3 mo.s and fire right up. I am convinced there is something that would account for your problem. My pickup has sat 5 mo.s and started. The problem is finding someone smart enough to diagnose whats wrong. Few mechanics have kept up with what has changed in the tech end of autos.

Thanks Phyllis, it is lengthy and that's why my copy is all garbled and I was unable to share a good copy.
You're right, (Dave) dchamb and I disagree on this one Ira...I left mine off the battery tender for over two months and no problem......and it's an '02 with original batttery.
From all the postings I've read on various forums it appears that there have been battery issues with some '05's. So if you mask it with a battery tender you'll never get Ford to fix it. Just my opinion
Personally, I wouyld let it die and call them every time until it was fixed - unless you're out of warranty.

"The Wiz" mechanic called me today regarding my 2005 T-bird. He has had it on a machine for two days and there is absolutely no electrical drain on the battery. He called two other knowledgable mechanics and the answer is: I don't drive the car enough in the winter. The 2005 T-bird and 2005 Lincoln share the same problem. Too much electrical stuff on the car. He said the TSB 05-22-9 basically says the same thing. The answer is to buy a battery tender for the winter months. I definitely drive it more in the summer, but it doesn't set in the winter. I drive it at 3-4 times a week but not far. I definitely feel the mechanic checked my car thoroughly and I trust him completely because he is the father of a long-time friend of mind. It wasn't the answer I was hoping for.

Phyllis: Please allow me, but I still disagree with that assessment. I have a 2002 which is 6 years old with 12,000 miles. That's 2000 miles per year and never had a problem. I use battery tender occasionally, but forget it more often than not.
Like I said, if it's under warranty, I'd haunt Ford with tow pick ups. Just my opinion

Phyllis, I have seen the tsb 05-22-9. It is very detailed. The Birds have a lot of electronic modules which all have power supplied at all times. My conclusion is that the use of a battery minder/tender/maintainer use of probably once a month for 3 or four days is probably the answer. Short drives do not appear enough to give the battery the charge necessary.
