Re: battery cut off switch

My latest attempt.
The Battery Brain III I bought from Bill Hirsch just didn't work out. I was for 6 volt, but I don't think it adapts well to positive ground. ( A couple of buck down the tubes!)

I used the parts that came with the brain to adapt a simple battery cut off switch. On one end of the switch a flat metal
bar connects the switch to a battery terminal. The other side has a 90 degree bend and a metal battery post connected to it. I have never seen these parts for sale, but I guess you could make them if you were handier then me.

The switch is from Harbor Freight (about $10) and I used a bolt extender from ACO ($1.55) to connect the switch to the top of the battery hold down rod.

PROS: Not a lot more investment after buying the Battery Brain.
No modifications to the car, and I can take it back off in a few minutes.
It's easy to use in a place easy to reach.
It does what I want, disconnect the battery for safety and to work on the car.

CONS: I have to open the hood to get to it.
It's probably not the most attractive set up that you have seen.

Any comments or suggestions are appreciated.
