Petronix points to electronic conversion

Hey everyone,
I have a bit of a problem. I have just installed a Petronix points to electronic conversion into my distributor. I followed the directions but now the motor just cranks, but will not start. I think the issue is that I have a bad connection on the positive wire to the balast resistor, but I am not sure how to get the ignition wire and the petronix wire hooked to the balast resistor. Is it better to wire them together onto the resistor or splice one into the other?

Re: Petronix points to electronic conversion

I've never done a pertronix, but might be able to help some.

First, the stock fabric covered ignition wire in a Camaro IS a ballast resister.
If it's still there, you don't ever need or want two of them, one or the other up to you.
The instructions do call for a ballast resister? Most electronic ignitions do not. Some require a ballast or resister wire into the coil, but full 12 volts into the module.

If the last case is what you need, you need to remove the stock fabric covered wire, cut it 3-6" from the firewall and run it to one side of the ballast. Run the wire from the pertronix module to the same side of the ballast.
Then run a wire from the other side of the ballast to the coil.

Re: Petronix points to electronic conversion

The Pertronix module wants a full 12 volts to operate properly, and '68 Camaros didn't have ballast resistors; as Jim said, the cloth-covered wire is a resistance wire (does the same thing as the earlier-60's ballast resistors), and you still need that wire for the coil (+).

Re: Petronix points to electronic conversion

As stated, get rid of the ballast resistor and hook your resistor wire directly to the positive side of the coil. Make sure that the distributor wire is hooked to the negative side of the coil. With both wires hooked up, disconnect the coil wire and put it near a ground. Have someone crank over the engine and check to see if you get a good spark. If not, double check all your wiring.

Re: Petronix points to electronic conversion

Ok guys I am a bit confused.

Here is what I am looking at: Coil is hooked up to 12 volts, red wire from the coil to the balast resistor, wire from ignition and wire from petronix spliced together and connected to other side of balast resistor. Black wire from petronix spliced together with tach wire and hooked to black side of coil. From what I understand, I shoiuld be hooking the red wire from my petronix to the 12 v wire going into my coil (or another 12 v source)?

Sorry for the dumb questions, but this is round 2 with this conversion after blowing up a crane cams XR-1 unit (I am still learning!!!).

Re: Petronix points to electronic conversion

You need to hook up the 12 volt wire directly to the positive side of the coil and bypass the ballast resistor. You no longer need the ballast resistor, since you took out the points in the distributor.

Re: Petronix points to electronic conversion

Ok, I will give it a shot tonight. I will keep my fingers crossed that I do not blow the unit up a again. I will let everyone know tonight how it turned out. Thanks for the help.

Re: Petronix points to electronic conversion

Good news. Rewired the connections and she fired right up. Now I just need to adjust the timing. Thanks for the help.

Re: Petronix points to electronic conversion

Ok, I am still working on this issue. I got the car to fire up and run, but when I took it down the street it stumbled real bad when shifting into second and then died. Is this a timing issue? Do I need to adjust the timing when going from points to an electronic? It may seem like a dumb question, but I am a rookie here and need some help before I start taking things apart.

Re: Petronix points to electronic conversion

Set your timing and also check to see if you are getting vacuum to the vacuum advance on the distributor. Also check for a vacuum leak on your intake manifold and carb.
