Help on ignitipon setup
« on: April 04, 2015, 03:59:32 PM »
I built a 2 cyl Hoglet engine and I have 2 lead coil to use with it. The coil has 2 pos terminals and 2 grnd terminals.

The Hoglet doesn't have a distributor as such, just 2 magnets set a certain amount of degrees apart that rotate past a Hall sensor.

How do I wire the coil into the circuit that was designed in "2013" as "New Ignition Circuit"?

I understand how to do it with a regular single lead coil but not the 2 lead coil. I used it successfully on an opposed 4 cyl I built.

I really like the circuit although my understanding of electronics is nil

Also does this set up use a "wasted spark" in setup in the way the way the magnets rotate past the sensor?

Here is the circuit I'm using (see post # 47)

Here is the coil I have, it is off of an Evenrude boat motor. There are 2 + post. One on each side of the plug wires. How are these wired into the circuit. A simple crap-o-cad diagram will be be more understandable to me as electrical jargon might as well be Greek to me.




Will post pics later.


Thanks

Hi Ron,
If you have two magnets that means it fires the coil twice in a revolution which means that there is a wasted spark. I have the same thing on my V-twin. The coil you have is for a 2 cylinder engine that fires each plug independently, I presume from the fact that you said it has 2 pos. and 2 neg terminals. There is no need for that type of coil on your engine. S&S makes an ignition module that is capable of firing 2 plugs at once.

 Thanks for your reply George.

 I really didn't want to spend $110.00 for the ignition system.

 Is it not possible to use the coil I have?  I have built that circuit before and it worked with a regular distributor type ignition. It took me awhile and I scrambled my brains plus the first board but it's running on my 4 cyl "Mastiff".  But it used a single High tension lead coil not a dual lead coil.

I would say treat it as one coil and connect the two +ve and two -ve terminals together and then wire into the circuit as if it were a single coil, this will give a lost spark but one coil to each plug.

The S/S hoglet ignition has two coils and thats how they are connected if you open up the box, same with their twin spark ignition.

  Thanks Jason, I called S/S and he said the same thing. ( Gads my short term memory seems to have taken a long term vacation. can't recall his name).  He was extremely helpful. very nice
ed gentleman.  That kind of service is, sadly, missing a lot nowadays.

"Roy" made the first dual plug coil at my request, and it works perfectly. I recommend getting one, and will bring mine to CF.
