I was up on hard this past weekend fixing my rumbling noise, zincs and rub rail sealing. Plugged in to the power and realized the "reverse polarity" light was on just AFTER I switched on the main breaker. Did I wreck something? I unplugged the boat, but yard people plugged it back in again, breaker was off, but I think the charger bypasses the panel. Would it have damaged the charger?
