Connect Alternator B+ to charging system

[Bob666]

Hi!

I am mounting the Sterling to my Volvo Penta 2003B year 1993 engine.

Great Sterling manual:

Alternator B+ goes to house bank +. I will move it to Sterling Alternator IN according to manual.

Problem is, there is another cable from B+ on the Alternator to another electrical gadget on the engine:

Arrow points to the gadget.


The Volvo Penta 2003B manual:

Page 17 has an image, but it's not exactly like my engine. The connection scheme at page 20, I got model "B". Volvo's electrical schemes requires you to be Professor of Electrical Systems or something, unfortunately...

From that gadget goes a cable to house bank +.

To my understanding the Alternator B+ is connected to house bank + with two cables, one of them via the gadget. With alternators though, things can be strange and counter-intuitive?

Should I connect the cable from the gadget to the Alternator IN, or should it, against common sense, go the the house bank +? (Thereby shortcircuiting the Sterling?).

Thanks,
