Battery cut off switch

This cannot work, and if you don't believe me, try it

Start the engine, bring RPM up enough that the alternator is for certain charging, and then have a buddy go back and yank the disconnect. You will find that the engine keeps right on running

After going out and looking at my car you are right. I have a 4 post wired in. I am killing the ignition box and the fuel pump with the smaller post.
