I replaced the crane allison ignition with a pertronix ignitor. I also have a new flame thrower coil. I still have no spark. I took the dizzy cap off and left the ignition on and manually cranked the engine. The rotor went all the way around and still no spark. I checked all the connections and they look fine. I'm confused. Please help!

OK I ran a piece of wire from the +ve battery terminal to the Coil to ensure I have 12 V..OK...still no spark when I turn over the engine.....I noticed that there is a black and white wire that goes to the -ve of the coil ...the other end isn't attached to anything ...what should that wire be attached to??

First of all, did you buy a new rotor?

That thing with the bent contacts is an oil pressure sending unit. It's not stock. The stock setup is a small tube that carries oil all the way to the guage.

Take the white with slate wire off the negative terminal. It provides 12 volts during cranking coming from the starter. It should connect to the positive side.

If that wire with the red tape is the hot, connect it directly to the red Pertronix wire. Edit: sorry, connect both the hot and the red wire to the + side of the coil. The hot should be coming from the ballast resistor. Last edited on 10-17-2010 09:42 pm by Jensen Healey |

The Pertronix is just a switch. The hot 12 volts goes through the red Pertronix wire from the hot side of the coil. The magnetic switch in the distributor grounds the black wire (connected to the minus side) to trigger the coil. Last edited on 10-17-2010 09:43 pm by Jensen Healey |

Remove all wires from coil. Find the switched hot wire and put it on the + side. put the red wire from the Pertronix on the + side. Put the black wire from the Pertronix on the minus side. Check spark from coil. Pull the high tension lead out of the center of the distributor cap and hold near a ground while cranking.

The wire from the ignition switch. It's white and goes through the tachometer and then to the ballast resistor. On some later cars the wire has a built-in resistor and will only put out about 9 volts. What year is your car? Maybe that's why you have no ballast resistor. Crank the car using the starter.
