Blue Sea Systems – DC Voltmeter

I’ve been a fan of Blue Sea Systems gear for a while now, they make things that are built for the marine environment. My thought process is what works out on the open ocean will surely perform in our vehicles. I bought one of their brand new Mini DC Voltmeters. This will be my first impressions of the thing and general info.

From the Packaging:

Regulatory

The Blue Sea part number is 1733.

A 2 AMP Fuse is required between the positive leg of the meter and incoming positive.

This can either be directly wired to your batter with a cutoff switch for easy off on use. Or wired inline with your ignition voltage. I have a house battery on my system so I’m using a ON – OFF – ON switch so that I can check my Main or my House with the flick of a switch.

It’s not overly bright at night so I believe it will work well in a car as well.
