Question Another Battery Light

My Battery light came on about a month ago. I went and got my Alt and Battery's checked and found my battery's were low and Alt was Bad. Got new Alt and charged the Batt's and everything was great, Then about a week ago my Batt light started flashing sporadically here and there, seemed when I hit a bump or shook truck it flashed so i tightened everything down. Then sometimes my power increased when i hit a bump..... But it would make it go all the way to 18 then drop back down to normal. Now it just started losing power slowly, so i my Alt and Battery's tested again and they said everything is fine

Any advice would help

Up date,

My battery light still flashing when i am driving, because it showing the same thing as i said before. My question is where is the voltage regulator? Is it apart of the Altnator now or is it a different peace?

Voltage regulator is in the altenator. How about checking the ground. A bad ground may cause your problem. I suggest go to a different place and get your batteries tested and your altenator tested again. It don't cost nothing to have the test done. But I would check all your connections and all your grounds as well.

I went and got all batt's and ALt done at a different place and they said it all passed. When i check the grounds, what should i look for, and is there a ground on the Alt?

"Update"

My truck ran fine for another week, now I can see my batt level go down when I drive for a long period. Sometimes it gets recharged but most the time it gets lower. And my truck will have plenty of juice when I stop driving and when I go to start it again... dead or not enough power to heat plugs and turn engine over.

Are my Batt's dead were they can’t hold a charge anymore?

Or another new alternator, because I know you may have to go threw a couple of crap ones to get to a good one?
