Here's a question that's been on my mind for a while. In fact, I've searched through some threads on Miata sites but didn't see what I had hoped to find.
I have a battery disconnect switch with the little red handle that I want to install in the trunk. The main purpose of this is to protect my car and my house when I leave the car sitting still for a week or 3 at a time... And, it could also be helpful and slow down some fool who wants to do naughty things with my Miata.
The question is: Would you wire the switch on the positive or negative side of the battery? I have a '94 NA, and we all know the positive battery post is easier to get to, but I have a concern with brass/copper lugs on the bottom of the switch being wired "hot". Should I be concerned about that? (I'm sure I could fabricate some protection for the "hot" wires & connections.) Should I wire it to the negative side of the battery and not have any more sleepless nights worrying about this?
It just seems that shutting off the positive side of the battery would offer the car more protection from something grounding out (shorting out) when it's least expected? I'm not an electrical engineer, but I did stay at a Holiday Inn Xpress...
Thanks for your input. Out of town tomorrow. I'll check back Wed, the 28th.
