Pretronix Ignition Conversion
Help! First time on here so sorry if I'm not doing this right. Have a 74 stock 350 4 speed. Installed Pretronix kit in the original distributor cap (per instructions) and car won't fire. I simply hooked the red and black Igniter wires respectivly to positive and negative terminals on stock coil. Currently I have two wires coming from the fire wall (one is black and the other is silver cloth and both are factory soldered together) going to negative post on the coil. There is only the new red wire from the kit and a capacitor wire going to the coil positive terminal. Any one here have any advice or pictures to share?

Which Pertronix unit? If it's the Pertronix III you will need full 12 volt power with ignition on to the positive on the coil as indicated above by CG. The factory points resistor wire going to the positive on the coil is only about 7-9 volts. The resistor wire can be taped and set aside. If Pertronix III you also need to replace the coil. I just did this conversion. Working good.

I have the basic Ignitor (1181). So I think I got this, Silver/cloth wire to +on Coil, black wire coming from firewall is not used. Ignitor Black wire to - on Coil and Ignitor red wire to + on Coil a well as a 12 volt source from Ign.. Ill try this later after my home town parade (that I won't be driving my vette in)
Thanks or the help, I'll let you know how I make out!
