Here is a little electronic ignition that I made for a rotovator that has a dud magneto. it is based on the wiring diagram for the TIM 4 (I said TIM6 in the video in error) Which is a 12v adaptation of this jerry howell ignition: http://www.model-engine-plans.com/partskits/ignitionsystems/transistors.htm. I have not soldered a circuit board before so I found it a good task to learn on. it uses a TIP 42C transistor, a 2N 2907 transistor and a 3144 Hall effect sensor. All of these parts are available on Amazon, see links below. I used a standard 12v lucas ignition coil and a standard Lucas 12 v battery. This system will replace the points condenser ignition system in the Lucas SR1 Magneto that this engine had originally. I have made a wiring diagram to show you how it is laid out and a circuit board placement diagram too. I hope this helps you! Please like and subscribe!!! Thanks for watching.

What do you do about advancing or retarding the ignition with this board?
Hi can you please tell me if its a 6v or 12v system. very well presented
Is this working with AC or only w DC
Thanks for sharing
After 6 years… thanks bro
This item can be found with the old royal enfield cb point
Sir explain digrams
How are you that into electronics and that's your first time soldering
Hi there, thank you for the informative video! Why is it necessary (indeed is it necessary) to have the two transistors? Why not go straight to the TIP42C? Many thanks!
would a solid state relay in place of TIP42C be better?
Does the coil get hot with the system on and not cycling? A timer that shuts down the saturation of the coil while not pulsing would be optimal.
Wiring Diagram? That would be very helpful.
what is the input voltage plz tell me thankyou and what are the changes when i use for 6v ignition coil
Old school can ignition coils typically have the + always connected to the battery (through a fuse of course) and the negative side is switched.
Danke. So sick of DOA Chinese CDI Boxes
Spark duration is the most important part to an ignition system. Your engine on its design and tune like air fuel ration will depict the spark duration and not all engines are equal. The original Atom company that was selling these stopped for this reason. You can make sparks all you want but if that spark isn't the proper duration then it's going to run the engine with a loss in performance and there will be extreme wear and tear.
is that resistor connected to the small 2N2907 low power transistor need to be 5 watts? because if i build that in actual and that big size 5 watts resistor is used and i will enclosed the finished product inside the distributor housing then its very tight in there.
I was wondering because 2n2907 is It is a 0.6-ampere, 60-volt, 400-milliwatt transistor and i wonder why 5 watts resistor was placed. Thank u.
hello in my circuit the 2 transistors and the resistance of the Led are getting too hot. ??? because if I have the same components as the diagram. ???? without coil they heat the same just a little less
Looks easy and interesting. I'll try one on a non-working Briggs & Stratton engine.
This schematic simply doesn't work, all you'll get is smoke and and a burnt out out TIP transistor. The fact that the model works just tells you the schematic and model are different. Find another, don't waste your time and components on this one.
I built this circuit foR use on a motoRbike, it didn't work, just burnt out the power lead from the battery. I must have checked the circuit a dozen times, still no luck, just burns out the power lead from the battery. Interestingly, when I connect everything up and just scratch the power lead the spark plug fires. Didn't work for me, I'll search for another diagram.
Very good job ! Now in add an arduino for adjust advance curve ignition with speed. With this website for help http://loutrel.org/StroboDuino.html
Hello sir,
Everything is working fine
But transistor is getting hot and then short!
Please get me the solution!
Thi is very good idea… thank's man👍
Can we use 100ohm 1/4w resistor istead of 1/8w because in my city 100ohm 1/8w reisitor isn't available. Also, 200ohm resistor isn't available. Can I use 2 100ohm 1/4w resistor in parallel for 200ohm 1/4w resistor.
Thats very interesting, would you expect this system to survive the temperatures/rigors of a motorcycle magneto, I have a few old trail bikes with dilapidated points ignition that I would like to try this on.
Is there a video where you show this installed and working on the rotovator?
Did this circuit works on 6V ignotion system also?
Hi what capacitor did you use thanks
I've been looking for a trigger circuit like this for a long time. Randomly this video popped up in my feed. Great detailed video. cheers.
does tip42 works on car battery
