Battery Disconnect
I am thinking of putting in a battery disconnect for a few reasons. First, for security. Secondly, to save the battery from draining while it sits for an extended period of time and even for safety purposes. My question is does any one have any recommendations of a switch to use?

Its a good idea, ('cept when you forget, turn the key, get out & retighten the disconnect, then start 'er up again) Harbor freight, JC Whitney, or any car show. Be aware of side or top terminals. They are different types for each application

I prefer the **** type because it doesn't have as much exposed metal and because I put my disconnect on the positive side. That way, I can disconnect the battery AND be sure there is no possibility of a short occurring when I'm working on the car.

I've been using one in my '75 that I bought at Carlisle several years ago. It has a green twist off **** and cost less than 10 bucks. I think it was a good investment in saving my battery since I don't use the car all winter.

make sure you get a small wire with a 3 or 5 amp fuse and run it from the battery terminal to the power terminal so you can keep any settings you may have in your car (e.g. radio). If you forget and go to crank the car the fuse will blow.

Also if your courtesy lights draw more than 3-5 amps opening your door will blow the 3-5 amp fuse in the jumper.

I have the **** type so I don't have as much big metal to short out. It's easy to just turn the **** a few turns to disconnect and turn again to connect. Also don't put it on the positive side with all that exposed metal and don't put it on both.
A battery disconnect is a good idea not just to save your battery over the winter storage but it is a good safety device for these old cars.
