have you thought about wirint that via a seperate set of wires directly to the camper battery?
i wonder if there would be any benefit?
hey Mark! opinion here?
battery info to the 10th of a volt is important.
the meter impedance should be such that it would present a better view if it had its own electrical path to the battery....i think.
Jeff, first off I hope you will accept a response a year and three months too late. I only saw this post tonight. I am sorry to have missed it.
As you observed, the panel meter's impedance should very high, so any voltage drop due to long wires should be considerably less than 1/10th Volt.
I'm more interested in having the panel meter hooked in front of possible open fuses. Blown fuse = no reading.
BTW, I got an analog meter from the local Fry's for six bucks.
