The meter itself is energized from battery #1. For example, if only battery #1 were to drop below 7 volts, then the meter doesn't start at all, but if only battery #2 were dead, then the meter starts, and displays zero volts for battery #2. I used a 1.75" diameter hole saw to install on fiberglass. The backlight is adequate.
My only complaint is that the terminals on the back are so small!
I looked all over the place for a round dual gauge and this is the only one I could find. There are cheaper options out there if you want to clutter things up with more than 1 gauge or if you want square.
I really like this gauge and I am very happy with my purchase.
If you're planning on installing this permanently, kudos to you. This is really only a gauge, so you'll have to open up your dashboard and cut a hole in it. I lacked such motivation. To mount it, I used stiff baling wire, wrapped one side of it to an old CB mount, then wrapped the other end around the backside of the bezel on the gauge, then screwed the retainer ring against this. When I upgrade RVs, I'm definitely taking this with me!
It has a backlight. The backlight is very bright. If you're stealth-camping, people might get tipped off by the light that emanates. The light is not very easy to enable/disable - it's a jumper(think computer motherboards) on the back of the gauge. If I had all the time in the world, I would wire this jumper to the ignition(or maybe an external switch). Part of me is also concerned that, if I park it for a few days with the backlight on, that it would drain the battery a little - I'm not so sure of this, though. Maybe someone more experienced can educate me on this.
Overall it's great kit, the only reason I knocked a star is for the price. I feel it's a little high given the simplicity of what it is.
I'm not using this for a marine application. I'm using this for dual batteries in my truck. Firstly, and again, the connections/lugs are way too small for 14 gauge wire. Secondly, the unit fits in a 1-3/4" hole diameter--which is a non-standard size in automotive land--and held to the mounting surface with a 2" diameter plastic nut. This means you can't mount it in an auto pod and bolt the pod somewhere like an accessory gauge, and if you flush mount the unit like it's designed to be, the surface needs to be pretty flat. Lastly, there are two tiny prongs sticking out of the back of the unit covered with a removable plastic cap: with the cap on, the unit's backlight is on, and with the cap off the backlight is off. Again, these prongs are tiny/delicate and very difficult to solder to/connect if you wish to integrate the unit into the vehicle's dimmer system or add a separate switch to control the lighting.
Conclusively, I'm happy to have this as is; however, hopefully this -1 star feedback will help lead to a specific auto/rv version that so MANY people are looking for and never find because it doesn't exist. This is the closest thing out there right now, so beggars can't be choosers.
