Battery Disconnect Kill switch Negative side?
I got a CRX and I'm moving the battery to the trunk area, I got a NHRA approved box, now I'm looking for a disconnect switch. I was wonder can you use a disconnect switch for the negative side instead of the positive side, since it still disconnects everything.
Also, can I have my alternator output wire go to the starter terminal (my fuse box is under my dash)? Since the only draw will be when it's starting and the alternator isn't working then anyway, and when it's running the alternator it on and starter isn't drawing anything (and the power from alternator just goes back to the battery).
Also, if a disconnect switch doesn't say NHRA approved is it still good? I know those cheap plastic ones probably aren't approved, but what about the nice metal ones.

Im not the best to give advice, but I believe, once the car is running off of the alternator, not the battery, killing the battery/negative wont do anything. It will stay running. You have to disconnect the power and alternator with the switch.
Only thing that I know about the switch, is it cant be plastic. Has to be metal. Dont know what switch you are referring to, but its probably ok.

When you disconnect the negative on the battery, then the alternator is powering the car. The battery is basically just a capacitor in parallel to the system. The actual negative would be back at the alternator, since electricity returns to its source.
BTW, I believe I bought one from Jegs. It wasnt that expensive and rated for plenty of current.
