Service Battery charging system

(2006 Buick Lucerne)
Service battery charging system light came on and I experienced symptoms of a bad alternator. I had my alternator replaced (150 amp) and after installed, the light was still on. Then, about a month later my starter went and I had it replaced. Now my car is running but the battery light is still on, (and my headlight is dim, and more irratic electrical behavior when fog lights are on) The car hasn't needed a jumpstart though,

you must have the 4.6L engine.that alternator is computer controlled,not by a regulator on the alternator,and can only be tested while mounted on the vehicle.have it tested.most parts houses will test it for free.Must have a full charge on the battery to test it.

Yeah 4.6L CXS. I ran through a lot of batteries while my alternator drained them. I'll try that. I just hope it's not a bad wiring harness or something. Thanks

Hey guys, I have a 2006 Buick Lucerne and I'm having that exact problem with my car right now. The battery is just dying on me while I'm driving. I bought a new battery yesterday and now today it's dead. I had went to auto zone they charge the battery for me and then did an alternator test and said I neede a new alternator. But you guys said the problem was still continuing after getting alternator replace??

I'm having a similar problem myself. I also have a 2006 Lucerne and last week the Service Charge System light came on. I replaced the alternator and the car started right up. I turned it off and when I went to start it again it kept clicking. I replaced the starter thinking that was the problem but it's still clicking. Had my battery tested and its 100% charged. Why could the problem possibly be as to why the car still will not start. Every time I turn the key it's just a fast clicking!! Do you think it's something with the computer and it needs to be reprogrammed? I'm desperate for help!

maybe the other two will reply back with what they found out to be their problem and fix.if they still have the same e-mail,then they will see this,and should reply.again, i want to say, Alternator Regulation: is>> Computer Controlled!
