So .05 amps for mine then...probably about the same for the link Pro...So Im buring up .10 amp hours, or 2.4 amps per day....thats a lot more then I figured it would be I have to admit....I figured it would be in the milliamps as well.

PicassoIII Oddly enough Ripple has a 12v lighter built in so we just run a cheap plastic voltmeter that plugs into that. The 'lighter' is switched along with the depth gauge and instrument lighting.
I wouldn't 'hard wire' it to the batteries. Definately put it on a switch.
A current meter isn't a bad idea either but, same deal, it should be on a switch. The only things we have straight off battery are the automatic bilge pump and the radios.

Stillraining Just food for thought.

Volt meters are cool and necessary...but I find a digital amp meter in addition, to be worth 10 times its minuscule power glance will tell you if something got left on when leaving the boat or hitting the bunk....took me 5 min one day to find the .5 draw it was telling me we had.

A dim light in the forward head which appeared to be off when looked at with the bright sun comming through the port....only way I eventually found it was to start switching off circuits till i located the culprit...then It was a hole lot easier to find once narrowed down.

btrayfors Both analog and digital voltmeters draw some current, but it's a very small current....on the order of 1ma for analog meters. The "waste" is from the resultant heat and light.

Of the ba-zillion things to worry about on a boat, this isn't one of them. For all practical purposes, voltmeters don't "waste" enough energy to be a consideration.

No, Yes, Maybe....

My understanding is that the analog ones do not, but then that volt meter is switched on my boat between off (center) or left or right on a spring return to measure voltage for banks one or two.
I hear that there is a very small drain for the digital meters, but have not confirmed that.

Does a volt meter waste electricity?

Hey guys,

Weird (stupid) question: does a voltmeter waste electricity?

Thank you
