Budget electronic ignition

Hdonly · May 6, 2021

I started on this project a few years ago, collecting parts. Life got in the way along with the rest of the "stuff" on my list. Decided to get back on it in between other things. Decided to use a new distributor so my Jubilee can remain operational while I fiddle with this project. Using a proximity sensor to detect the lobes on the distributor shaft that will fire a 4-pin GM HEI ignition module. I got the idea for this from an on-line article for racing riding lawn mowers and garden tractors. Even though I will have to modify the distributor a little, it will always be capable of going back to points.

ice project. Keep us posted.

I hope you know that the current location of your sensor needs to be rotated 90* for it to see one of the passing lobes. Also you don't want the working temperature to be over 140 degrees as this sensor breaks down close to 170 degrees. Too many variables for this setup to work, sorry.

I put the ign from a 90's Ford Tempo on a
50 Massey Ferguson. But had to buy a box
to make it advance. 10 deg for every 1000
rpm. Bolted the crank pulley 34 pin sender
to tractor crank pulley. Total cost was
around $200.

Rotating it would be easy, but didn't know about the temperature issue. Now going a different route. I have an old Pertronix magnetic ring for this distributor. Burnt the Pertronix module out because I left the key on without starting too long. I found a $10 magnetic pickup that I think will work with the Pertronix magnets. It too should trigger the GM HEI module.This pickup will withstand 225F. Should stay cooler than that in the distributor with a lot of it outside the distributor.

Looks like I won't need the magnetic ring from the Pertronix kit with this sensor. It has it's own magnetic field.
