Battery cut off switch

Before I install my battery back to my A128S this season, I'm planning to put a cut off switch to it. I normally just pull the fuse installed outside before the the battery box. When I put the fuse back I hear sparks, I don't like that because it is close to the front storage box where I store my gas containers. Here is the link of the switch I'm planning to use Princess Auto
I'm not sure if this completely cuts off the power or allow small current through for accessories like the radio. What do you think?

This will make it easier for me to turn off the battery to the trailer and also when I charge the main battery directly with my solar panel.

My trailer is still covered and a foot of snow around it, this time last year I already have it ready for my first trip....

I see yours in many units, but never used it. I installed this one on my last Wildcat. Simple, cheap and never any issues.
Less than $5 at walmart and other places.

I use the same one as spierce617. No key to keep track of. Works great.

I think it matters where you put the disconnect switch as to what will be turned off.

If you want everything off disrupt the ground lead.

I just called my store branch and they have it in stock. This switch cuts off the power completely and that is what I want. I plan to have this switch in line with the wires outside the battery wrap with electric tape.

Where do I connect the line? Positive or Negative line?

I am not in favor of using the ground lead for the switch, but it would work. Otherwise just use the positive BATTERY cable beore it goes anywhere. If can be selective on what you disconnect, if you want, but then you are kinda disrupting the purpose of the disconnect in the first place, and you battery will draw down over time. If you want to keep the radio hooked up, then at least determine what specific wire is the one that keeps power to the electronic portion of it, and determine how much power it takes. AND then determine how long your battery will hold up to that discharge a .25 amp draw will suck a group 24 battery down to 50% in not much more than a week.

Battery cut off switch

If I want to put a cut off switch inside the trailer, where in the A128S I could find the wire to cut?

Did any one installed a battery meter in their trailer? If yes, how did you connect it? Pics will be great and a link to the type of meter you used will be awesome...

Battery cut off switch

I just ordered this voltmeter from Amazon
http://www.amazon.ca/gp/aw/d/B00CDJM...6118077&sr=8-2
I'm planning to attach a lighter plug to the battery, which I'll use to connect the solar panel and/or this voltmeter.
