So, I bought this QuickCar 50-864 switch panel to replace the ignition and key start, and to provide switchable cool shirt, electric fan, lights, windshield defroster, accessory powered devices, whatever. According to NASA, the battery relay or disconnect has to be in front of everything, just off the positive battery post, so when the solenoid is disengaged, the power is removed from all electrical items, with the exception of the electrical trigger for the fire system, if one is included in your car.
Based on the wiring on the back of this panel as it stands, there’s a solid aluminum main buss bar to which all the switches other than the momentary plunger attach, with a red 8AWG wire feeding the main buss, and it seems like everything would be made live by engaging the solenoid, but I was counting on engaging the solenoid with the panel, so I can kill the car totally when the switch is down. Is this not how I should be doing it? If it’s okay to use a switch on the dash in conjunction with the kill switches for the emergency workers, and have them only live when the main switch is engaged, I can wire past the buss bar on the back of this panel, directly to one of the switches. Then I would wire them so the emergency safety switches wouldn’t even have power unless the panel switch was engaged, and thus the solenoid couldn’t engage, without the dash switch engaged. Sort of two layers of security. If there’s not supposed to be a total kill switch on the dash, too, then how do you guys do these panels? I’ve seen them in several cars on the race footage, so I know guys are using them, but the video is typically not clear enough to read all the labels, and of course we can’t see the back of the panel anyway.
