Keeps that fat wire line to the starter cold except when starting the car. Put the ford solenoid in the trunk right next to the battery On your 4 pole switch wire the alt like the one healtservices posted above, not like the one in my example. Make darn sure the cut off switch can handle the anticipated amp load. I HATE, yes HATE, to see cars that have that hot line from the alt to battery live all the time. If you've never seen a car burn to the ground because of it, it's a real joy. If you do put the relay in the alt line like I have, the way this one is wired is for a race car that the switch is turned off after every run. The relay will be a continuous draw when the master cut off is left on. If a street car, connect the trigger terminal to a switched key source instead of the downstream side of the master cutoff.

Actually I would have the wire from the battery disconnect go directly to the starter. 5951892-4prongdisconnect3.jpg (3271 downloads) Last edited by HealthServices; 04/28/10 12:30 PM.

I want the 6-8 ga wire carrying the load vs that 1-2 ga or larger, huge line running to the starter. If each got grounded which carries the greater potential for damage? Yes my cars carry a bit more wire, but, you throw the cutoff switch and nothing outside about a 1.5-2 ft cube in trunk is hot anywhere in the car.

I may still change mine over but because the system is already wired on my car and I have other items I'm still working on it's on the back burner. I would put a continuous duty solenoid for the alternator though.

I carry a jumper so if the relay were to fail at the track, I can jump around the relay and be no worse than the constant hot alt line method. If you get tricky, you can use a weather-pak. Also, I usually have a spare relay with me so it can be changed if necessary. Knock on wood, I've never had a S605 fail yet.

No draw if master left on and no live wires leaving trunk with the master off. Motor dies if switch flipped 5951958-Rxtrunkbattwire.jpg (14999 downloads)

But the NHRA rules makers haven't ever seen the light. However, if you aren't racing at a NHRA track then putting the switch on the negative side might work better.

And to the OP you would just cut the original wire from the Alternator to the Bulkhead. The Ameter will no longer work.

Otherwise if you have a MSD it's just a matter of rerouting the small red wire to the secondary terminal on the master switch, rather than use the alt wire. Here is a diagram that should work with a MSD. Note the small red wire on the MSD is only a trigger wire so voltage lost across the long line is not important. 5954339-trunkwithkill.jpg (8402 downloads) Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first.
