Battery fluctuations

I noticed my gauge will drop suddenly at hisay speeds then return to normal. Repeats every few seconds..21 Bighorn crew with E Torque Hemi. Anyone having this issue?...24k miles.Runs starts perfectly..

If it runs and starts perfectly, I don't believe you have an issue to resolve, but not overanalyzing what the volt meter is doing might be a start.

It never did this before. So you think it's normal? It drops about 50% for 5 to 10 seconds, then returns to normal with no lights or additional load on it? AND repeats in 15 seconds .without stopping.Never seen any charging system do that before. But no CEL .

Continued for a few days then went back to normal.Couple weeks later started again.Stopped by dealer, was told if no CEL, no problem. 2 days later, at 6 am, dead battery!! Guess it was a problem.
