My new van buildout thread
I figure I will have a lot of questions so I should put them all in one thread :). I got a new van! Well, an old one, but new to me. It's in another state, and I won't see it in person for a few m...

I don't know what you mean about the monitor. Do you mean the shunt? Yes the shunt goes on the negative battery cable usually. Think of the shunt as a batwing door with a little trigger switch attached to it. Think of the electrons flowing in and out of the shunt as people. At a given point in time you walk over and look at the monitor and can see how many people have gone in or out of the battery depending on which way that batwing door has swung. On the side of the heavy shunt are 2 very small terminals wire 22 or so gauge wire that go to the monitor like the trimetric. Those wires are carrying the message of how many people have passed in which direction.
If it's a positive number it means people are flowing in. If it has a negative symbol in front of the number it means people are flowing out. As these people move back into the battery some of them fall to the side because they leak out through gaps in the "tunnel" (wire). We will call that loss of people"resistance". If we were to count how many people we lost we would call it voltage drop.
There is also internal resistance in the battery. In the end we have losses in the system when people come out and go back in. SO, the trimetric makes up for that by letting us program in an amount of inefficiency.
As you well know, there are no free lunches. Everything takes energy. If you take 100 ah out of your battery, you may need to program for 110 ? or so to go back in.
All this stuff may seem daunting. Just read and absorb. There is nothing here that you cant learn and conquer. In the end you will think it was no big deal. You don't need to become an engineer or scientist. You just need to learn basic dc.
