I have 4 batteries (2 house 2 cranking) and want to be able to monitor their voltage. I've bought 2 voltmeter guages but they came without wiring diagrams. I figure that they must draw some power so should be on a switch rather than conected directly to the batteries. Is this right? If so should I use a seperate switch or can I conect them to the battery isolator switch so they're powered when I switch between bank 1, bank 2 and all? Thanks
