Exterior light issues

I bought a 2006 Ford freestyle used a week ago and I had the alternator replaced because of over charging. I got that done this morning. Last night when I went to start it I had to be jumped. On the way home I noticed that my blinker light was faster than normal. This morning I had a family member come and take the car and change the alternator and bring it back to me. I’m not sure if he used turn signals or not (he lives in the country) but he didn’t mention anything to me and I forgot about it till I was driving to work today. When I got to the parking lot I left it running to check out what bulbs were not lighting up and neither of the back ones are. Also, my high beams aren’t working, and neither are my break lights (the one above the truck hatch is working) so I thought that I had blown some bulbs. I went to the advance on my lunch break and they checked a couple of fuses and said they visually checked the high beam and break fuses and said they looked fine. So I bought some bulbs and when I got home I hit the lock button on my key fob and my rear break lights work. I have googled like crazy and the owners manual doesn’t have any mention of this. Does anyone have any ideas?

Once a year, my blinkers blink fast and my key fobs wont lock/unlock the doors. Lasts for a day, and next morning everything works again. I know Im not alone, in seeing this temporary problem.

Some reports on the internet of the use of non Ford branded alternators can cause problems. The PCM expects a exact voltage from the alternator, and it may not be in the range its looking for with an aftermarket brand. Not all aftermarket alternators are a problem, people have used them and said everything was fine, and others say after they exchanged a couple of them at the store where they bought them, they decided to put a Ford Motorcraft alt. on, and the problems stopped. Usually they also had a battery warning light that wouldnt go out with the aftermarket alts.

Any time you have to be jump started, you should go to a Advance or Autozone, etc, and have them use their test meter to check the output of the alt and condition of the battery to find out why, and if either is 'bad'.

Who told you the alt. in your vehicle was overcharging?

Advance was the ones who told me about the over charging. This light issues happened before I even changed the alternator. Everything was working fine besides needing to be jumped cause the battery was weak from being over charged. The night before I got the alternator replaced I had an issue getting it jumped. It took a couple of times before my car would start. On my way home from getting it jumped was when I noticed the blinker lights going faster than they had been before.

And the alternator that was taken off was also an aftermarket one
