Has anyone installed a battery kill switch under the hood?
Given that a lot of what we do with our vehicles involves disconnecting the battery before we begin work on things, and for those who winter their vehicles in a garage for months at a time, it seems like this might be a really good project to do. The problem is, I have no idea where to begin, or what might be best. I see many of them have amperage ratings. Do you need to match the cranking amps of the battery for this purpose, or am I off on a tangent?
What I'm thinking of is something that might be bolted to the side of the engine bay near the battery, with a nice "red" turn key. Turn it one direction, you have a live battery circuit. Turn it the other way, and you break the circuit. In general terms, that's what I'm contemplating. Finding that, mmmm, not so much luck so far....
I looked on Amazon, and I also paid a visit to Canadian Tire earlier today. CT has a switch that is purely mechanical. You remove the negative contact, and bolt it onto this copper flange, and then you place that flange over the negative battery post and tighten it down. To kill the battery, you loosen the connection. I'm not too keen on that as it seems to me like there's still the change of a connection being made and the circuit going live. Here are a couple of links to Amazon that show what I'm talking about.
This first one is like the one I saw in CT that I'm not so keen on. It also looks a bit butt ugly as well (IMHO)
This is one possible choice:
And this is the one I really like the looks of. I think it's intended for a dash installation, but I'm still thinking under the hood near the battery...
Anyone with experience in this or recommendation, please chime in with your thoughts and links to any products that might fit the bill.
