Electronic Ignition help needed.....

Need some help getting this Nova II system to work...this is on an old Ariens with point system. So, I've got the module mounted/grounded, and have the lead from the coil (which was connected to the side of the points unit with a nut) connected to the module lead, and the kill wire. All three wires are wire nutted together.

BUT, it seems like there are two wires coming out of the coil (not including the plug wire)and I've chalked the one closest to the condenser. Am I connecting th wrong wire to the module?

Ideas please....

Sorry I cant help as I have never done this myself.
What is the third wire that you said you wire-nutted together go to?

Thanks dbert -- one wire is from the coil, one from the kill switch that connects to the throttle, and the last one connects to the positive side of the Nova module. THis does have me stymied.....

I have never installed a Nova but, the wire you have chalked is the coil ground and is in the correct position. You may want to remove the wire and clean off the rust in that area. Have you tried reversing the leads on the nova module like the instructions show? Also make sure the carb is set to fast speed so the kill wire is not grounded. You could also remove the kill wire and try it with just the coil wire connected to the nova.

Experience is something you don't get until just after you need it.

I posted this schematic before. Hope this helps. Your chalked wires are grounds.

So, even if you get this going, how are you going to set the actual ignition timing? Seems to me you would have to use a timing light and a flywheel marked in degree.

Whats so bad about points and condenser. keep it simple

Have you really spun the engine to test it? Unlike beaker points that will crackle at the fling of the flywheel the solid state systems usually need real flywheel velocity to fire.

OK -- finally got spark after confirming the wiring, and put the shroud and recoil back on. Then connected the module to the shroud to assure good ground. Tryed it and no spark. Tried the reverse polarity and that was the ticket. Noticed a bit of a jolt in my hand, so knew I had spark. Tryed a different plug and got a nice arch. So, now it's time to move to the carb for a thorough cleaning. Then....change the oil and try to start it up.

Thank you all for this help.

Glad to hear you got it working. You do realize that you now scared all the snow away and you won't need the blower until next winter.

Ain't that the truth! My lady friend bought a Path Pro 6 weeks ago... I think she now has buyers remorse.

Yep, we all know that the simple act of buying a snow blower will cause all the fun white stuff to stay away. As I say to my friends....I live in Massachusetts, and I'm as far south as I want to be. Spent 6 years in Fairbanks, Alaska and loved it!

Now onto a follow-up....I do have spark, which this morning was easily visible, yet still can't get the machine to even cough with ignition.Is it possible (or likely) that my coil is too weak to generate a spark? I've put in a new plug to no avail... Fortunately I've got an extra flywheel and coil off a similar engine that I can switch out if need be...I'm also going to hook up an electric starter and see if that quicker turnover helps any....we'll see.
