Need a little help wiring my on/off switch since I moved the battery to the truck. What is the correct way to wire it up so it will work correctly. I currently have the large gage wire hooked up but not quite sure which of the other wires on the solenoid needs to be run back to the switch. Any help would be appreciated.

James,

The alternator's charging wire must be routed to the cut-off switch in the trunk. So that when you turn the cut-off switch off the engine dies. So don't connect it to the same terminal on the cut-off switch as the battery lead.

steve...does that mean my battery cutoff switch that only take the battery out of circuit is illegal? the only reason i got it was i have an electric fuel pump and trunk mounted battery. if mine is wrong then how should it be...details please. coupster, wanna tell you how my cutoff switch is set up (hidden) so that nobody will ever know the "deal". its kinda trick, saw it in a magazine and did mine even better. take out the backup light lens, run a rod through that to your cutoff switch (mounted on a steel plate) in the passenger rear wheel well. thread the ends of the rod, one end will be double nutted to the switch lever....used a white "pushbutton style" disk (like you see on machines in big factories" right where the backup lens was. blends right in the rear of the car, very slick. you should see how i got my 2-step switch setup.....i love this stuff. this will be a push/pull switch now....best way is probably pull on...push off.

Chip,

Yep! Sorry

When the starting line crew sees a problem with your car that you don't they need to kill all power to your car with that switch. And if it isn't switching alternator voltage the car will keep running and pumping fuel, etc. It's not that hard to do and is a good thing. You also have to have it labelled for them so they car run up and know they have to push it to kill the power to your ride.

ok, which alternator wire? just run the wire along back to the same switch then back to the alternator right? i never noticed this on race cars before...maybe cause they run off the battery..no alternator, right? anyway, the labeling thing will totally kill my whole stealth thing.

I run an alternator on my racecar. As do most of the guys I race with on a weekly basis.

Chip,

Somebody else is gonna have to help you with that, cause I cheated and ran a AC/Delco single wire alternator. The output wire from the alternator goes directly to the trunk on ours.

With the antique '67 alternator/regulator with the wires going thru the ampmeter in the dash I'm not sure. Sorry,

oh well. dont really pay much attention to electrical systems on dedicated race cars. have seen lots of them without alternators (LOTS) and running multiple batteries. either way, if you, kid, know how to hook this up then speak on. steve, i got that gm setup on my '49 pickup.

It's the field wire that is routed through the shut-off switch.

I routed the charging wire of the alternator with 10 ga. wire back to the on/off switch. I hooked the wire up on the battery side of the cable not the side that runs back up to the solenoid. Just tried it out and it does shut everything off and kills the engine. I guess I'm legal now.

Thanks Steve you were almost right. It does need to go to the battery lead side of the switch, not the solenoid side.

Later!!

DUH! I was thinking dyslexicly. You're right of course!
Glad you figured it out.

If someone just runs the field wire to the batt, the alt will keep charging after the switch is thrown.
