I used to use a battery post type power cutoff switch, but it was junky so I bought a summit switch type, the kind guys with trunk batteries use. There are alot of wires coming to the positive side, so it was easier for me to cut the circuit by stopping current on the ground side, rather than on the positive.
Is this a bad idea?
I have to ask because I just looked at my car in storage-- and all the aluminum on the engine appears to have oxidized way worse than it ever has, with the worst part being concentrated on the alternator.
I can't think of a theoretical reason why it would matter where I cut the power-- but? in real life? Anyone who has experience with this? Thanks!

Matt, doesn't matter which you kill. Since you should always disconnect the neg side first anyway, sounds like a winner. That is what we do on our boats, just lift off the neg cable.
