Battery Disconnect/Kill switch
Information overload!
What is the correct way to wire a 4 pole battery disconnect/kill switch in a Miata?
What about 2? One internal and one external.
Yes I searched around on the forum......................................
Thanks in advance

I would strongly advise that you determine whether or not your specific switch is designed to have the alternator current flowing through it. There are 4-pole switches which are, and some which are NOT.

^^ This. Many 4-post kill switches are only meant to interrupt field current on the second pole, not alternator output. Running one of those on the alternator output will make your car run like ****. And then when you shut it off with the engine running, it can cause further damage since it lacks a resistor to provide run-down load.

We keep the wire gauge the same as OEM everywhere. We use a high quality welding cable instead of the OEM cable. Same with the alternator wiring. I think the only thing we do differently than the Longacre diagram is a jumper between A and B (where the 175 amp circuit arrow is) and then run a wire from B back to the battery. The other B goes to the starter and the fuse block.
