On the boats electical panel the "reverse polarity" light is on both when (a) we are plugged into shorepower or (b) when we turn the invertor on.
If the reverse polarity light was only on when plugged into shore power
then that might mean the problem was in the shore based power supply which would seem more easily resolved.
There has always been a faint light on the reverse polarity light which I believed was caused by the close proximity to the shore power
Looking at it now both lights are on but the reverse polarity light is not as bright as the shore power light or any of the other lights.
What could cause the reverse polarity light to now be on when running on the boats internal invertor. Is there a test or something I could do?
Is it possible that we could have been affected since plugging into shorepower and now have permanent damage?
