I like to run the alternator to one because when the switch gets thrown, there are NONE, ZERO, ZIP, NADA hot wires beyond the cut off and the relay. Nothing hot outside the trunk. Running the alt + to the battery keeps that line live at all times. For those playing along at home requiring a visual:

I can't think of a way to do it with a single set of contacts like most switches that I've seen. I've never put a lot of thought into it either. The easy way to do it is to put the switch on the negative side of the bat. But evidently the tech guys at NHRA aren't smart enough to allow that logical solution so they insist on the switch being on the positive side. Having the switch on the positive side causes several issues with the charging circuit but NHRA refuses to open their mind.

Fire wall still needed if fuel cell is in the trunck area and also the box needs to be NHRA approve for that. Not just a battery box like a marine use box.

This is to shut the engine off and prevent fires from shorted wires after an accident, the same reason you always see the fire department cut the battery cables on a car after a collision hard enough to damage wiring. Why is it that a rule is put in place for your safety and then people have to try to find a way around it? These switches are a no brainer to hook up. Take the cable coming from the battery to one side of the switch, connect the other side to everything else (thru the starter relay or whatever).

I put the switch on the driver side rollbar tube that runs from the top of the main loop to the rear of the car. Then a long rod or a chute cable can be mounted right above your head so you can also operate the switch from inside the car. If you have a problem on the track, your the first one there, so you can kill your own power.

The switch must be on the positive side because if it is on the negative side and in a crash the neg. cable is cut or chafed it will provide a ground making the switch useless. Call Mark at Mad electrical 559-539-7128 he will sell you all you need to do it right. Website is www.madelectrical.com I followed his instructions and have had no problems at all. The switch can be on the main positive cable but I had a hot start problem with mine wired that way. Mark's way of wiring it solved all that and is NHRA legal too. 2003 Bristol Dragway Sportsman Champion 2016 Bristol Dragway Power Hour Champion

I saw in one of the pics a "Borg Warner S605 Continous Duty Relay".... (is this the Ford solenoid that people use?) ps RobX,,you da man,,great pics/diagrams,,i saved and printed all of them for future reference. Last edited by 69CHARGERMD; 01/15/09 05:16 PM.

It's the interchange info from napa with part numbers for the relay. Can't take credit for any of the diagrams. Someone else posted them and I did the same... clicked and saved. They do come in handy!

I also put the link to MadElectical,,,, i might get this one,,,has the wires,,and solenoid,,,and the price was pretty good.... http://www.madelectrical.com/catalog/st-1.shtml

I currently have a cut out on the neg side right now with the Batt up front, I think I have worn out my door hinges with going in and out to turn in on!! I always forget, Great idea, two methods to control the power! Thanks! ED

69CHARGERMD master Joined: Jan 2003 Posts: 4,852 KENTUCKY	Smokin' good pics.... I need to re-wire the Belvedere,,,,and put in a solenoid,,,and run a wire up to the alternator....to make it right. Question: Where did you get the wiring you have,,,,and how did you know what gauge to use for what .... thanks, Doug ps,,,is the way you have your (+) cable running from battery,,,,,to the kill switch,,,,,and then to the starter how you did it ? ( wont this keep the large,,batt cable running to the front of the car hot ALL the time when teh kill switch is in the on position ? ),,, in the first diagram that Rob posted,,,the batt cable looks to go thru the solenoid,,,,( i suppose in that case, the batt cable would only be hot during starting ,,,and then "dead" while the car is running ?),,, I hope i am making sense,,,, not sure if i am missing something ? On the Madelectric site,,,they also show the large batt cable going thru the solenoid,,, I have to figure out how to wire mine....... Doug Last edited by 69CHARGERMD; 01/15/09 10:20 PM.
