Electronic Ignition for Onan CCKB

Recommended Posts

midnightpumpkin

I just discovered that copy paste from the other web site works.

 

Well, I ran the engine with electronic ignition today. I am very happy with the result. Used the orginal Onan coil and a condenser from Autozone (U1515).

The engine starts instantly and the timing is rock steady when I put a timing light on it. Before there was jitter in the timing,even running at constant RPM.

Two areas to be aware of in making this conversion. 

1. There is a small 3/16" ball bearing in the bottom of the socket that supports the governor shaft in the timing cover, it is prone to getting lost. The fork on the governor shaft needs to be centered in the round area inside the timing cover.

The cover on the left is the one set up for electronic ignition, note the fork is below center because the ball bearing is missing.

2. The governor disk that pushes against the governor shaft has to be positioned with the hole that has a metal insert at the 3 O'clock postion. There is a roll pin in the timing cover that goes into this hole to keep the disk from spinning.

Other than these two items, just follow the orignal writeup from Smokstak.

The red wire from the sensor goes to the + side of the coil as does the condenser wire and the orginal wire which is hot when the ignition is on. 

The black wire from the sensor goes to the - side of the coil, that is the only wire attached to the - side. The wire that went down to the points box is disconnected permanently. 

The is no ballast resistor and the orginal CCKB coil is used. Here is a picture of the sensor and rotor mounted with the new timing cover.

John, apologies if you have already discussed this but have you compared the Kirk Engines module to the setup shown in this post?   I like the ease of install but would like to hear your thoughts.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
