Default Installed battery cutoff switch today.

I finally had some spare time to put in the battery cutoff switch in the Tudor today.
Came out pretty good I thought.
I mounted it on the bottom starter bolt with the Snyderís bracket then ran one wire to a ground on the frame where the battery tray mounts, then ran another wire to the positive terminal on the battery. Let me know what you guys think. Iíll try and post some pictures.

Also I nixxed the original ground strap below the drivers seat because it won’t be used anymore.

An o.k. installation, but being under the hood makes it inaccessible in an emergency. It also means you won't use it regularly. A better installation would have the switch where it can be used from inside the car.

I really did give it some thought and it was too tight where I wanted to mount it under the seat. Plus I didnít want to cut any holes in my original wood so that helped me make my decision.
As far as thinking under the hood is a bad spot for it, the only time Iíd have to kill the power in an emergency in my mind is when Iím under the hood working on something anyways so that works for me.
I used all 4 gauge wiring and heat shrunk and tie wrapped and Iím going put corrugated wire protection around the tight spots. Or anywhere even close to touching any other metal that could chafe the wire.

Another reason I mounted it where I did is so (as many others have said on here) I can check the oil and give the engine a once over before every trip.

I was thinking about enlarging the hole on the vertical cross brace that the floorboard sits on but it would have been a tight fit next to the battery.
I did what I thought would work best for me.

Yes, a hole drilled through the wood floorboard behind the steel cross member. Very unobtrusive and easily accessed.



With the switch there, I can easily disconnect the entire system from the battery (which I do as I exit the car).



Problems of concern that the switch being easily accessible address:


* A stuck starter switch ( have seen happen).
* Stuck brake light switch.
* Reverse drain through alternator when not running.
* Short behind the dash panel.
* Theft prevention.
* Forgotten headlights or turn signals.



(I'm sure there are others, I invite contributions. :-) )


Edit to add a picture showing the switch through floor board, no carpets installed at that time.

I don't want to criticize, but, I think the wire is a bit light. I think #2 should be the minimum, [the heavier the better]. I too prefer the switch mounted inside or where it can be reached easily. But, thats just an opinion.

Contact area between frame and lug should be clean and bright. Antioxidant compound between them will prevent corrosion.

Like mentioned before #4 is to small for 6V, Bratton's sells a #1 or use 0 or 00 welding cable.

The amount and length of your cabling makes the gauge of 4, potentially more problematic. In the end, you will do it your way, but, you did ask for opinions.

A choke cable or maybe a bicycle hand brake cable will allow you to turn off power from inside the car. See the thread started by Doug Nichols on mar. 21 2018.

Looks good! I might move mine there after trying mine out for a bit.
