IGN Switch problem

I have a problem that I have yet to be able to figure out. I just put in my second new ignition switch and it starts the car fine but will not shut it off. When I turn the key to the off position the car just keeps on running. It a 27 T coupe and I running a rebel harness and have it wired just like the diagram shows. What am I doing wrong? What am I missing?

 

Your alternater "turn on wire" or if you have an electric fan is bleading back to the distributor. You can either add a diode, or move your alt wire and your fan relay wire to the "acc" side of the ignition switch and your distributor wire in the ignition pole on the switch.

 

I already have the fan wire(which is wired direct with no relay) on the acc side of the switch and I tried moving the coil wire to the acc side but it would not start that way.

 

what type of alternator?

 

If it is an internal regulator chevy, hook the fan wire and the exciter wire from the alternator to the acc pole on the switch and the coil/distributor wire to the ignition side of the switch. This should solve it.

 

^^^That's the one!^^^

 

I have a GM 3 wire alternator

 

Are you using a resistor system where there are 2 wires on the + coil post? If so, maybe the other wire is connected to the wrong place. If it won't shut off the coil + is getting power somewhere.

 

I'll give it a try thanks for the help! I appreciate it!

 

Then just do what I said. The exciter wire is the smaller of the two coming out of the plug. The other two go directly to the batter off the alt.

 

Could possibly be a chinese aftermarket switch. They Suck.

 

I have one wire from the pertronix unit going to the + side of the coil and the wire coming from the ign switch. That all. I'm not running any type of resistor.

 

Many guys wiring for the first time have this issue. Its just back bleeding. I will bet when you hooked it up, the distributor (+) wire was on the same post as the alternator exciter wire.

Usually with the electric fan wire on the same post, it runs for a bit and quits. The exciter wire will run forever.

 

I sure hope this fixes it! Pretty observant on your part to know that this is my first full wiring job.

 

Been doing it that way for 20+ years on hundreds of cars, never had one go as of yet, including my now 12 year old daily driver.

 

Could call Glenn and he will walk you thu it while you are looking at the car.

 

This might sound strange but try running your ignition wire to the acc on the starter switch

 

Well, I ran the excitor wire and the fan wire to the acc pole on the switch and guess what? It worked!! BUT the volt meter says the alternator is now over charging. So I called the guys at Rebel (who are alway very helpful) and he said that I need to add the diode to the excitor wire.

 

yup like 440 said run the exciter wire to a warning light OR a to the ign switch via diode ONLY. all my cars have a warning light or gauge.....cause i like to know.
