Re: Master Cutoff Switch
Coincidently, NHRARacer.com has a battery question this week. I never had or plan to have a car faster than 9.99 or 135 mph. but I never knew or even noticed that they apparently need a cut-off regardless of battery placement. External switch also?

Re: Master Cutoff Switch
Your alternator wire and battery cable should be on the same post on the switch. The other post on the switch will run the cable to your starter solenoid.

Re: Master Cutoff Switch
Travis, I’m guilty of not having mine labeled. Thanks for the reminder, I will address it.

Re: Master Cutoff Switch
I had a double pole Moroso to kill the alternator until a short at the starter burned it out. I replaced it with a single pole rotary at half the price wired like this and it works fine. No engine run-on.

Re: Master Cutoff Switch
This is the simple legal way to do it without extra wiring, solenoids, etc. You just have to be mindful that the alternator lead is always hot, and pay attention to making sure it is protected where it is routed and when working on the car..
