New here so I say hello.
Some advice on car 12v please.
I want to fit a dual volt and amp meter in my dash, and have one with the appropriate shunt. My expectations are, when the engine is off it will show the state of the battery. When the engine is on it will show the active volts and amps?
I assume I can wire to the cigarette lighter socket with is always on?
As I don’t want the meter ‘always on’, I’d believe I can fit a simple on/off switch on the positive side. However, would a common accessory switch do the job or do I need a beefy high amp type?
Thanks, Dave
