Alternator problems

[Butch Smith]

Anyone replace their alternator? The "check charging system" just popped up on my dash . I had the battery tested and needed a new one, so I have done that, but the light comes back on after the car has been running for aboput 5 min. The lillte battery light also comes one at the same time. I figure it has got to be the alternator. I have checked cables and made sure the connection is good. How hard is it to replace the alternator. How hard is it to release the pressure from the belt tnesioner?

I did mine. It literally takes minutes to do. You just need a breaker bar or long rachet to release the tension on the belt. Just take your time and you will be fine.

Butch, where are you located in GA.? I'm west of Atlanta in Temple. There can be other causes to your problem but one of the first checks is the alternator output. Have yours tested and verify the readings if you go to one of the national parts stores. Output voltages should run between 14.0 and 14.5.

as stated...get the alt checked and replacing is too...TOO EASY...i did mine...are there any other indications about the charging system...i would have a hard time cranking and lights flicked...dimmed with other accessories on...even cut off on me a couple of times...then one day...ran into work for 5 min and came out to a dead truck that wouldnt keep charge to even turn the wheel...roll the window up/down...anything..new battery and still had the problems...new alt...fix it

Took the alternator out(it is very easy to do) and had it checked, It is good. So now the battery is good and the alternator is good whats next? Expedition cranks up good and runs for about 3 min then the check charging system light comes on as does the little battery on the instrument panel.

Might be the wrong alternator. I bought a high output aftermarket one and when I put it on the battery light came on. The guy told me they make two different regulators for the alternator in our trucks and I got the wrong one which caused my battery light to come on. Swapped the alternator for the one with the right part and im good now. I would look into that

what is the amps on the alt

 

[Butch Smith]

Didn't have to replace the alternator, the stock one is still good.

After all of that stuff it is the alternator. Went to the dealer and he checked and said the alternator was about to go and it was kicking in and out.

New alternator in and all systems are running great.

I'm glad you're problem is solved, but did you check to see if it was the voltage regulator or the brushes?

Dealer said it was a voltage issue. The old one was only putting 12.5 amps.

Hi Guys facing this problem at the moment. I know I need to change the Alt as it is not charging.

Not sure which one to buy. I have an 03 5.4 Eddie Bauer 2 wd fully loaded.

Any help would be appreciated. Thanks.
