I posted on here about an electrical issue I was having with my 2005 Mustang GT. I had changed the alternator 4 times 2 ourselves and two by a automotive shop. Each alternator was bought from a large chain dealer. We found out,finally, that the alternator we were buying were not compatable with the card. We ended up having to go to Ford and have a Ford alternator put on. It cost of $800 for parts and labor but I was willing to pay anything to figure out why the alternators kept going out. It has been two months and the card runs great. I was told by Ford that it is some type of chip that needs to be compatable with the computer. At this point I didn't care because my card actually is running now.

Well okay, checking for a battery drain should be simple enough. That seems the logical next step.

this morning went out there and the car started right up and has been working fine all day... still no auto up on the window. Maybe a relay or a regulator?

Has the car been scanned for codes? Maybe there is a module or relay that's malfunctioning and it might store a code.

I got a question about my car i was driving it home one day and i stopped at a light and the car just died. soi get to the side of the road i mess around with battery cables and nothing so i call my friend and have him jump my car and its on and running perfect again. Until i turn my car off then it wont start so i get my battery checked and its bad i replace it and get the alternator checked its good.So im driving and the battery gauge on the cluster is flickering back and my electric locks,interior lights, and speedometer is not working?????????? but my car is running just fine. So my check engine light comes on and i have a scan tool in my car and when i plug it in it wont pick up the cars computer???finally i was going home to visit my parents and i pull over to by a drink when i come back outside my car sounds like its dying like its not getting fuel i had a full tank??????? but when you shut my car off it will start just fine.could it be water in the electrical????ground?? I dont know. any suggestions?

Have read above posts. Have had the same problem w/ '05 GT off and on: Get in, engine turns over very slowly. Get "low battery" readout on the radio and my radar detector. Time on radio needs to be reset. CD changer clicks thru all CD's.
Problem is NOT battery. When battery tender is hooked up, green light indicates battery fully charged. Thus there can't be a drain on battery or alternator problem.
I always leave radio turned off.
Once during routine service at dealer, was told battery not charging properly. After 35 min's, manager came back and said it was OK. He probably couldn't figure it out.
Empty the CD changer? Leave it in the garage without turning on antitheft? Why not. I'll try anything.

Btw, how do you lock car without turning on antitheft? Lock it with key?

don't go by the battery tender's assessment. Unless you load test a battery, you really can't tell its condition. When the tender flashes the OK, all it means is that the battery won't take any more charge---that could mean it's full, or it could mean it's faulty.
You are probably right, but the one thing that always trip people up and makes them crazy when working on a problem, is making assumptions that something is okay without really verifying it. It's time-consuming to be thorough but it pays off.

Right you are, Host. Battery was dead as a door nail the next morning. Who has patience (or time) for this kind of mechanical failure? Following day got replacement battery, 40R Sears Die Hard Gold -- don't you love that allusion to corporate overcoming of death?
