The new ABYC standard requiring ELCI circuit breakers on shore power service to boats is an attempt to reduce the amount of stray electrical current in the water - read below for an explanation of what this is all about.

Alternators
Question: I need to replace my alternator for a Yanmar 3YM30 /2006. It is a Hitachi 60amp and I am thinking in replacing it with a higher amp output. I might then need to replace perhaps the pulleys for the water pump and the crank shaft and then of course consider a serpentine or other type of belts. Would appreciate your suggestions?. Thanks.

What does an alternator regulator do and how does it work?
Posted by Peter Kennedy on 5/1/2014 to
Alternators
What does an alternator regulator do and how does it work? An alternator regulator supplies current to the rotating part of the alternator. The rotating part is called the rotor, and when current is applied to it it becomes an electromagnet. Its rotation generates an alternating current in the fixed windings of the alternator, called the stator. The regulator acts as a control mechanism for this process
