Question on wiring for battery meter
When I installed my solar system last year I installed one of the more inexpensive battery monitors and it is working well enough for my needs. However, the way I wired it into the system shuts it off when I switch the battery cutoff switch to off. I knew this going in but was concerned that the draw of the meter itself was just one more vampire load and I didn't want that. Now after reading more on the amount of power it would use and some of the limitations that wiring method creates, I want to switch the monitor to the "external power" setup.
The attached picture shows my current wiring method ("A" in the picture) and what I am looking at changing it to ("B" in the picture). I believe I can just remove/trim off the lead going to the +VExt terminal (it gets it's power from the downstream side of the cutoff switch). Then run two new wires from the positive and negative terminals of my battery bank and attach them to the +VExt and -VExt terminals.
Since I'm not a whiz with electronics like some folks on this forum I thought I'd ask before making the change. Am I looking at this right?
Thanks all!
