Another battery light flickering problem!

Seen a million posts with these lol. First time for me it was the alt. Put a new alt in from auto-zone. Not sure if its a reman looks brand new with a warranty.

That was only 3 weeks ago. It got 2 brand new batteries in the last month as well. I did the heater plug delete and the wires just hang. Looked like the positive wire was leaning against a bolt tonight so I moved it not sure if it fixed it.

Problem is that randomly a few days ago while driving the battery light started to flicker slightly no loss of power or anything. It pretty much does it only when I am on the gas or the cruise control is on. When I let off it shuts off again. VERY intermittent. Did it at idle earlier today. Instead of turning off when you hit the gas (Bad alt) It comes on! Wtf!?!

Any help appreciated!

Thanks,
Josh

Make sure that the small plug is fully seated and in good condition on the alternator, check connections of the larger lug, beyond that I would have the alternator bench tested.

Tape that wire from the AIH up and put some heat shrink on it.
