Electrical cutoff switch

Well, it's been over a year since I last posted anything here, time really flies when you overworked...

I have been busy with work, but recently found time to do a little work on the Roadster.  I managed to install an electrical cutoff switch between the battery and the frame.  It works well.  Here's how I installed the setup.

I had to enlarge the hole in the cross brace behind the battery so I could mount the switch, amazing what a simple rat-tail file can do in just a few minutes.  Once that was done, I installed the 19" #1 gauge battery cable on the positive terminal, ran it through the gap between the transmission and the body to one side of the switch.  There was only about 5" between the other side of the switch and the nearest hole in the frame cross brace.  I didn't have a wire to mtch that so I used a 5" section of 1/2" copper pipe.  I flattened the ends 90 degrees from each other, drilled the mounting holes and bolted it on.  oh yeah, I also ground away any paint near the brace mounting hole to make for a good connection.

By the way, I did this entire post from my tablet...

Here are some pictures:
