My battery and brake light flicker intermittently, like many posts in this forums apparently, but I've gone above and beyond trying to track down the issue and no luck. New alternator(2 weeks old) good battery, checked connections and even had it taken to two different shops to be looked at. I'm running in circles but I can't seem to figure it out. One of the shops recommended putting in an OE alternator but stated they're not even sure thatd solve it. It doesn't even happen consistently, just whenever it wants. What am I missing?

 

Check battery connections and the connections to the alternator as well as the alternator fuse, but especially if it was a reman alternator there's a chance it could be bad out of the box

 

battery connections are good. Im not sure about Alt connections yet just cause they're so hard to get to. I'll check the alt fuse next
