Over the last day or so we've noticed that we see a red flash on our shore panel lights. It's always been constant green as far as I know but every min or so we see it flash to a red light for maybe 1/4 of a sec and then back to green.
On the panel it says that this is reverse polarity. We haven't noticed anything cutting our or any error lights on any of then chargers, etc. the batteries are saying they are fully charged at 14.1v.
Any ideas? Is this bad for the batteries?
I haven't noticed this before, could it be the local shore power
Any advice would be most welcomed.
