Electrical Question (with photo)
My wife and I just purchased a motor home (Forest River 3100SS) and I was looking in the battery compartment and have a newbie question.
In the attached picture, I have a yellow arrow pointing at what looks like some sort of rusty modulator (?). I'd like to replace it but I don't know for sure what it is. I have a dual battery 12v system.
First, what is it?
Second, can (or should) I replace it with a shunt?
Thanks for your feedback.
