[Public-list] Voltmeter wiring

[Daniel Sternglass]

Gord,

To have the voltmeter to show the selected battery's voltage, you need 
to connect the voltmeter's positive input to the OUTPUT point on the 
switch. The other side of the voltmeter goes to any available 12 volt 
ground (which will be common to both batteries).

When you set the switch position, it connects one or the other (or both 
batteries) to that output terminal on the switch, so your meter will 
read the voltage of whatever you've selected. By the way, I swear by the 
little digital panel meter I installed 3 or 4 years ago to know which 
battery to charge with my tricle charger.
