? why did you replace alt. assy. What is your battery voltage with eng shut off ? now start and run eng at 1000 rpm and check voltage at battery,
it should rise up to 14.2 to 14.6 but not much higher.
 
If voltage is not within spec. check ALL battery cables from battery to starter and battery to ground ( BOTH ENDS ) must be tight CLEAN & TIGHT
 
Let me know

It's not a voltage issue. The alternator was replaced becuase it was not charging (11.5v). The alternator that is on it now is working fine. I've already checked the voltage, which was over 14v under full load with the A/C on high and the high beams lit. I replaced the terminal ends today becuase I did find a .5 volt drop from the terminal end to mid way down the starter cable.. The headlights/dash lights still flicker badly and the gauges still sweep back and forth occasionally along with the shifting issue where it seems to fall out of gear when the lights flicker and all of that. I'm just going to replace the computer and pray that does the trick. I can't think of anything else that would cause this variety of issues - and I did find one instance where someones dash gauges were sweeping back and forth and replacing the ECU fixed it.

The car catching on fire was a blessing. I wish ours would catch fire.. =)

I've seen the insturment cluster cause a bunch of goofy problems and need replacement.
 
Also, I think you have an acc. modual (mounted under dash, about mid way) that controls all
acc. radio, gauges, door locks,wipers, heater, but I'm not sure about the the headlights. that
may be a diff.problem. I would not be in a hurry to replace the main computer.
Keep me posted,

Okay, so you're not the first one to say that, apparently. My roomate already has a new gauge cluster sititng in the garage. I think she had read that someplace else and ordered it but never had it put in because the shop she used in the past told her that wasn't it. I'll throw that thing in tonight or tomorrow and let you know. Thanks!

Okay, so I just swapped the insturment cluster out with a fairly new unit. It only has 30k miles on it. I started the car and the gauges aren't acting up, and I'll be damned if the headlights and dash lights aren't flickering anymore. I haven't driven it yet, but I'd be willing to bet that the shifting problem is gone too - since it all seemed to always happen at the same time. I think it's fixed! I really appreciate the advice - I was ready to replace the computer - I would never have thought an insturment cluster could cause so many issues. Thanks!!

My husband has a Ford Focus and my son has a Ford Escort. My son has had to give up on his Escort and I don't know if any of this is related or not. From the time he bought it, he had a headlight that he had to replace several times. Then it reached a point that it didn't work so he changed the fuse and that seemed to be the problem. Then it started all kinds of electrical problems. The fuse buned out, the headlight went out again as did some other lights. He replaced the alternator, battery cables from the ground and the car would not start. It was towed and they simply did some tweaking on the battery and cables. Sometimes the lights, inside and outside, would just go off and then come back on and then go off again. This went on all the way to work one day. He also discovered that he had no tail lights so he drove with his flashers on. He stopped the car at work one day and it wouldn't start again. They had to tow it in for the second time. This time they replaced the alternator and more fuses. The next morning he had the Christmas tree car again as he called it, with lights flashing on and off. The garage did more checking and told him to not spend another penny on the car. His fuses were burning out but everytime he replaced them, it was doing damage to the alternator and battery. It seems that whoever owned the car before had electrical problems and they could not find the real reason so they had installed several ground wires, which you never do to a car and thus it was ruined. The fuses had to just be removed in order for him to drive it home. Now he has a car that runs find in the daytime but he has no lights, no interior lights and the only electrical thing that works is the radio. The garage said it would cost way more than the car was worth to fix the damage the previous owner had done as it would have to be completely re-wired from the front to the back. They said that was probably what was needed in the first place as this seems to be a common problem with these Fords.

We have had a 2007 Ford Focus for several years (which we also bought used) and we love it. I have to have a van but my husband needed something that gets great mileage for work and the Focus has been wonderful. The only problem we have had (happened twice) was that it would not go in park. I found the answer on here (Ford knows about it but has done nothing about it.) There is a ring at the bottom of the gear shift and my husband just pulled it up and it hasn't happened again. We bought from a dealer we know and trust and he lets us drive anything we want for a day or two if we want to. We drove the Focus for a day and decided it was just what we needed. In fact, we were all set to sign the papers on a brand new Nissan (which is a good car too) but decided to go with the cheaper Focus even though it was used. We recommend it highly but then anyone can get a lemon so there are never any guarantees. No one model is going to be perfect on every car.

Better stay away from this 1, I will advise you to buy a CHEAP digital volt-amp meter $5-10
 
Cheak voltage across battery posts with eng running. should not exceed 14.2-14.6 Volts.
 
If it is over this it can boil the battery and warp the plates, ruin the battery and then burn up the alternator. This usually happens with cheap after market parts. INFO ONLY
