My car does not have any check engine light on at this time and Autozone will not be able to check it. It might be just that the alternator was bad... if it was then I learn my lesson for next time... but I will be take it to a shop to make sure that the pcm is good just to be on the safe side.
Thanks a lot Mr. Shiftright for helping me out.

Oh i don't think you have to do that...if the PCM weren't functioning, you'd know it. You might have the shop check all your battery cables, connections and ground cables however. You see, when the voltage drops, for whatever reason (bad battery, bad alternator, bad connections, etc.) your car's computer goes nuts---so we can't say with any certainly at the moment that the PCM was actually doing something wrong. It does, however, control the charging rate.

#154 of 200 ABS Module Failure
Aug 11, 2010 (9:01 pm)
I have a 2004 Mustang Mach 1 and the ABS Module has internally shorted out. Replacing the ABS Module looks easy enough, but is there any re-programming required? If so, what needs to be done?
#155 of 200 2001 ford mustage V6 3.8 electrical problem
Aug 13, 2010 (1:04 pm)
I have a 2001 V6 mustage and everyonce in a while the radio cuts off and the oddometor goes dim then back to normal when i have the headlights one. The headlights dim the first time. I changed out the alternator from autozone and a month later i had the same issue. I replace the alternator and now a month later it is doing again. i had a friend take a look at it and he did a quick check on the ground from the engine to the body and it was good. i took the car to ford and they checked it out within an hour and they stated that the ground is good. they told me to bring the car in when it happens again. I do not have any check engine light one. i have 150,000 miles on my car. somebody told me that it may be a fuse but if it was a fuse the system would be off. i was thinking about replacing the headlight switch hoping that they may cure the issue but then i was thinking that it might be a grounding issues. I still have the orignial radio in the car. about a year ago i had the dome light that would stay on after the car was shut off. i when ahead and remove the dome light bulb could this somehow be related.
#156 of 200 2005 Mustang GT Electrical Issues
Aug 27, 2010 (8:23 am)
I have a 05' Mustang GT and have had an electrical issue for as long as I can remember. I should mention that I had satellite radio installed in it very early on at Circuit City, not sure if that is relevant.
My car battery goes dead in a matter of days since new. Ford told me to make sure my radio is turned off before I shut the car off each time. I do this. Still the car goes dead quickly. Then they had me replace the battery. I had my dealer put in a new battery. I still have the same problem.
I saw on another "Ford Forum" site that supposedly there is an issue where the radio system draws 1.64 amps instead of .11 as it should. It says Ford is aware of this problem. I called my dealer and neither the service manager or the electrical guru service tech ever heard of the issue. I know I'm not the only 05 owner with this problem. I keep the car on a trickle charger most of the time now but the other day (with a full charge) after sitting at my office for 8 hours, I went to leave work and it wouldn't start. I waited 2 minutes and it fired right up like there was no problem but as other people have mentioned, the radio came on to AM540 and the CD's cycled through and the guages did a complete reset. Can anybody help me with this?

My understanding from various forums (though I don't yet own a Mustang) is that there are several draws on the electrical system when the car is 'off' besides the radio. In addition, the alternators aren't the best, so the batteries aren't always charged to full. Have the alternator tested to see if it's fully functional.
