Check for loose ground wire. Be sure battery cables are on all the way and tight. If you installed the red and green doughnuts on battery post, remove them, loosen cable ends and push all the way on to battery post. Tighten and check.
Have the new alternator checked out...flickering the headlights have nothing to do with the alternator...when you turn off the head lights just helps the alternator to send more voltage to the battery...when you give it gas it help the alternator increase the charge...you should not have to do all that...check you drive belt make sure is tight...alternator may need to be replace.
The thing is I can't get the alternator to work but only when I turn the headlights on and off a few times then you can see its charging the battery because I tested it with a volt meter and the they rise when you raise when you give it gas but when you first start the car the alternator doesn't turn on because you can tell the lights start to dim but once I turn my h eggs headlights on and off a few times it's like the alternator kicks on because the lights don't go dim and the car doesn't feel like its gonna die out The reason I replaced my alternator the first time is because my battery light came on so I replaced the battery but the light still didn't go off so I replaced the alternator then had my old on bench tested and it passed so I'm not sure what else to could be could it be a relay or ecu problem?
I can get it to work*
did you check main fuse box(fuse #30) and dash fuse box (fuse #24)
Check the battery voltage when you first turn on the car?
Sounds like the battery could be low when you first turn on the car...by turning the headlight off it helps charge faster...headlight draw a lot of current.
The battery won't charge at all when I first start it but once I turn the headlights on and off a few times it will start charging as if something triggered the alternator to turn on but shouldn't the alternator turn on right when you start the car?
Yes it should....is that every time you start it or only in the morning
Everytime I start it I have to turn the headlights on and off to get the alternator to turn on
I've replaced all the terminals and made sure there was no corrosion checked all the fuses still the battery light stays on and wont charge unless I turn the headlights on and off a few times
do you have the correct tension on the drive belt?
You will need a volt meter to check battery voltage to see what the alternator is doing
where did you get the alternator?
I got the alternator at o'Reilly's
I would exchange for another one! on aftermarket alternators you will need to try a few before you get one that works well
I had one replace on my work truck and the light flicker when on idle, but they are to lazy to replace it.

SOURCE: Volvo 240 wont hold charge
if with the volt meter the amps go down while running and at increased rpms than your alternator is not charging right
SOURCE: NEW ALTERNATOR, NEW BATTERY, CAR still dies and wont start
Check the main power fuse that goes to the alternator output. if the alternator went out it could have burnt this fuse also.

Hi:
Though your car seems fine without using the headlights, you have a charging problem, and need to get a couple things checked out. First make sure your battery connections are clean and tight. Your alternator belt should also be checked to make sure it is serviceable and properly tightened too. Your alternator should be checked under load, and lastly, your battery too. Most auto parts stores, such as auto zone,will check your parts for free,so you should only be spending money on what is broken!
