Yanmar 1GM10 - Smoke, No Power

[chihuahuas]

The voltage drop is maybe 1 volt. Some warming may occur on the wire run as this increases resistance and doesn't create a problem as long as the wire is rated for the amp load. The main idea is to locate the batteries farther away from the alternator. The fools the alternator regulator. The regulator is looking at the output terminal
and regulating from there. Adding a length of wire limits the amperage draw on the alternator. Think of it as the same as using jumper cables.

This idea is useful in a situation where a real small alternator is running a large battery or bank of batteries.

Although a coil of wire presents a magnetic field and one would use canceling loops to stay away from interference to AP compass and all that.

I must be misunderstanding your post.
“Normally”, one might put a diode in the alternator “Sense” line, creating a 0.6V drop, thereby fooling the alternator into INCREASING it’s output.

Hey teach, do I get half credit for saying it in post #15?
