WARNING..shore power ON, engine ON is a NO-NO


Just got back from some sailing, as we landed a few friends were discussing in a friend's boat.

The boat almost caught is the deal.

He had several problems with his Alternator, and had to change them twice before.

This time it almost set fire to the is why..

He has his boat with the shore power allways connected, every single day.

3 times a week, a care taker starts his engine (and mine) and lets it run in neutral at higher everyone here does.

Turns out that his alternators are being damaged because the shore power is connected while the engine's alternator is also charging the batteries...

I always have disconnected (for more than 20 years) the shore power when we start the engine, but here its not a comon practice, annd most run the engine whilst still on shore power.

Normally the alternator's are protected with a bridge or something, but...never knwing..

So be warned, if you run your engine, make sure you disconnect the shore power, just in case.
