The charge in the batteries is fairly consistent, if a little lower than it should be with stronger batteries. We are on shore power, which is functioning as it should be. A body else seen this before?
Have you tried disconnecting from shore power and seeing if they still flicker? While I was at Lewisburg a few weeks ago, my 12v
LED interior lights were flickering while I was on shore power, but when Lewisburg had a power outage and I went on straight house battery power, the flickering went away. When power was restored, the flickering was back.
that the flickering was due to low AC voltage to the battery chargeró while my Airstream was plugged in to shore power it wasn't actually using battery power, but rather power provided by the charger. And since the flickering was not
evident when I was plugged in to shore power at other campgrounds on my way back home from Lewisburg, that only reinforces my opinion that the flickering was due to low shore power voltage at that one campground.
