Delco 4 Cylinder Ignition PerTronix 1143 Ignitor Review

Ideal for replacing point problems. I've only had them on two different small 4 cylinder applications and I was surprised that the job was easy. Just two wires and everything works. The only thing I would change is that if you leave the key on when it doesn't work, they can burn out.

Highly recommended. Installed on my father's '53 Ferguson TO30 tractor with a Continental 4 cylinder engine and an original Delco distributor. The tractor is now so stable, starts and idles. No more points! The manual recommends a 3 ohm coil. Don't worry about a 3 ohm Pertronix coil, you can use a 12 volt ignition coil from any old air-cooled VW. I went to the parts store and bought it for a '69 VW. This is the only 12 volt 3 ohm coil and it works great.

I converted my Ferguson TO30 tractor to a full 12 volt system. The Pertronix module was the final step in the point and capacitor upgrade. One of the most important points when converting 4 cylinder engines is to use a 3.5 ohm ignition coil. Many coils have a resistance of 1.5 ohms or less, and a 3.5 ohm coil was, for me at least, crucial for the conversion. It's been a few weeks now and I couldn't be happier. The tractor starts much better and easier than with the old points and condenser…
