The kill switch still does not kill the car right away.It runs for about 1-10 seconds longer.I have tried everything I can think of and every thing you came up with last time I asked this.
The only thing left is the eletric fan.It has a relay wired right from the battery side of the solenoid.And a wire from the fuse box ACC fuse.I noticed today the kill switch only acts up when the fan is on.I disconected the battery wire from the fan.And the kill switch worked great twice.
Plug the fan back in runs after I kill it.I called flex alite they said there is NO WAY it could be the fan or the realy.
What do you guys think,about the fan and onther ideas. Ron ------------------

Part2,
I installed a one wire ALT,and mover the charge wire to the truck at the kill switch.
My old voltage reg still is there,but the wires from the dist are discounted.There is a yollow that goes to the batt side of the starter solenoid.And my amp lite stays on all the time.I dicounted the plug to the voltage reg.The car started and ran fine with it disconected and the amp lite is off.But can I run ok this way.Or what should I do with it.Do I need the yellow to the starter solenoid hooked still.Thanks sorry for the long posts.It was just one of those days.Where I wish I starter working on my car. ------------------

DID YOU MEAN A ONE WIRE ALTERNATOR ??? AND IF NOT YOU CAN PUT A DIODE INLINE WITH YOUR FAN SO WHEN ITS ON ITS NOT BACK FEEDING THE ALTERNATOR.. oR BETTER YET PUT ON THE ALTERNATOR ..HEHEHEHEHE.bRUCE

Yes I did mean an alt I fixed that.  I could hook the fan up to the alt and not the batt?
Not sure why not?

Ron a diode is a one way valve like piece that you can put on the wire from your alt to your battery and if something is backfeeding your alt it will stop the flow so it wont want to keep running after you shut it off..Bruce

Ron,Why not just move the wire for the fan from the battery side of the desconnect switch to the "switched" side of the battery disconnect switch? The only time you won't have power to the fan is in an emergency situation. Otherwise, the fan will operate normally as long as the switch is turned on.

Here's how I have mine hooked up. I'm using the stock alternator and I had to remove the black/yellow charging wire from the red alternator post and tape it off. Then I ran a new 8 guage red wire from that post all the way to the kill switch. Then I hooked the short positive battery cable to that same side of the kill switch. Next I hooked the long 2 guage cable to the other side of the kill switch and ran it all the way to the post on the starter solenoid. The negative battery cable is bolted to the trunk lid hinge bolt that goes into the body. Then I added 2 HD ground straps from the firewall braces to the bellhousing. Everything should be powered from the solenoid terminal at this point.
Nothing else should be hooked to the charging post of the alternator except the new kill switch feed.
Hope this helps. ------------------

Dan that is EXACTLY how I hooked mine up too.I've tried 3 different switchs too.
I can't figure this out,it only does it once the car warms up alittle.It seems to only do it when the fan is running.------------------

It worked for me, so I guess my electric fan has a diode already built in to keep it from being a generator. That's all it could be.------------------

I don't see why you couldn't hook the fan to the one-wire alternator since it has a built-in regulator. That would isolate the fan from the front harness when the kill switch is off.------------------

Where can I get a diode and what size would I need ?Dan I was thinking about hooking the fan to the alt,dont see why that would hurt it. ------------------

Ron,You could run all your accessories off the alternator. All the wires on the solenoid's cable posts except the two battery cables, would be wired to the alternator's output post. Then everything except the starter would be switched off with the cut-off switch. Note, you may need a larger gauge wire between the alternator and battery.
I think this would work, I'll look at the '66 tonight. SteveW

Ron the fan is a permanent magnet fan. This is nothing more than a generator if the blade is turning with out power. Do you have the fan switched through a relay? The Painless Wiring kit for Aux. Fans has a relay that has a built in Diode in it. Use a Relay to switch the Positive lead to the fan and I think that your problem will disappear.

The fan was not turning without power.
Yes the kit for the black magic fan came with a relay.
The tech guy at flew alite thinks it maybe the fuse I'm using.He said that the ACC fuse is the wrong one to use,but does not which one would be better.Before I go changing all my connections around on the fuse black.Does this make sense to any one else?
Thanks for the help,I'm at loss right now.I'm affaird they wont let me race with the switch working the way it is now.I'm going to try the new track in frenly next firday.
I sure I hope to find something that works.
