Electronic Ignition Install - No Spark from Coils
Corbin <c_geiser@...>
As we wait for Klaus to get back with us, I thought I would throw it out to this group. As many know, I am installing a Lightspeed Plasma III electronic ignition system in my Q200. Following the instructions, we have followed the steps and got to the point where we are rotating the prop to get the spark from the coils. No spark so we are troubleshooting as best we can including reviewing the instructions for any missed steps.
Power from the battery to the circuit breakers is good and the signal coming back to the warning lights is good (if one coil fails a light comes on, etc.). However, we are not registering any power getting to the coils and have triple checked the wiring is connected to the ignition boxes going to the coils. Could it be that the magnet sensor is not sending a signal back to the ignition boxes therefore no spark? We wonder if there is a bad connection in one of the magnet sensors. The other area I thought it could be is that we are bypassing the keyed ignition for now. My avionics guy assured me that it is not an area of concern since the way it is currently wired, it is not an open-loop (key in off position). I still wonder though... If anyone has any known common failure points please let me know. We may try and go back out to the hangar this evening. -- Corbin N33QR |

That usually is a sign that the sensor is not picking up the trigger on the crank. Check the spacing etc. I have installed several of these in the past with 0 issues so it is probably something simple.

Not sure if Klaus uses Hall sensors or not, or if it even matters, but there may be a high pass filter on the input from the sensor, that effectively blocks the signal if the magnet does not move past the sensor fast enough. This could be a safety feature to prevent the engine from firing when RPM is below a certain speed. I am just guessing here, but the board that he has in the system is certainly capable of doing this if he wanted to, and it would be a smart thing to do to prevent the engine from kicking back. To test this, you could disable your fuel system, hook an automotive timing strobe to your coil output and then crank the starter to watch the strobe to see if you are getting firing pulses. My uninformed 2-cents worth….

I just went through the same issue on my Cozy installation. Everything checked out but still no sparks. Eventually traced it to the mini-sensor not being correctly aligned to the trigger ring. Aligned both in distance from and vertical to it. Question; can you get a spark by passing a magnet (South Pole) over the mini sensor?

A hall sensor measures presence of a magnetic field (or not). A simple magnetic sensor (coil) will see a “double” peak as the magnet passes. Not sure which type of sensor Klaus is using, but I suspect it is a hall sensor.

I’ve seen this in Velocity installations. Granted I have been retired for 4 years so I may be a voice from the past.
Be sure the ignition computer box is getting power and ground (I would measure it at the box connector). The ignition input must be un-grounded or the ignition in the L, R, or Both. When grounded the ignition system is deactivated. (you may have this connection wrong, try it both ways, open and shorted to ground).
CAUTION Turning the props could start the engine You may want to remove the spark plugs from all cylinders.
The alignment of the magnet to the sensor is critical. Turning the prop slowly may not give sufficient pulse to trigger the spark.
You could monitor the sensor with an oscilloscope and observe that the pulses are being generated.

It is a hall sensor. I once replaced one which was sheared off by the magnet.

Continuity testing a Hall device with a VOM will destroy it instantly. Just in case you were considering it.

Thanks, everyone.
I will answer the questions and some thoughts in this reply and then again as more come in. Yes, it is a Hall sensor. Looks as though most are thinking like us and that it is something with the magnet sensor alignment/distance so we will check that first. It is also possible we didn't rock the prop fast enough at #1 TDC....very likely as well. We will test pins 1 and 9 again...just in case we counted wrong. Good idea on passing a magnet over it and good to not to connect a VOM. Thanks!! As always, appreciate everyone's quick input! -- Corbin N33QR |

Follow up to keep records of information learned.
Klaus' best guess is that we just need to rock the prop a bit faster. He believes we have everything else correct. We will try that tonight and, if no luck, might just let the starter give it a go in order to see if it can get a spark from the coil. Leads are not connected, of course. -- Corbin N33QR |

Just start it up. Then you will know!

The pickup for the Electroair needs 500 ohms to check “good”. Ohm it out. This may be apples to oranges though. Different company.

Well, no luck tonight. No spark rocking back and forth at #1 TDC, no luck rotating prop faster, and no luck having the starter have a go at it.

At this point, I’m assuming the sensor(s) are bad. Ugh. Wishing I had never tried upgrading to electronic ignition at this point and ready to put the mags back on. Corbin On Nov 9, 2020, at 1:56 PM, Corbin via groups.io <c_geiser@...> wrote:

I ended up using a hall sensor for my tach input. While testing I hooked an LED up in parallel so I would know that it was working properly. Might give that a try so you can narrow down the problem and know if it is the sensor or something else.

Electronic is nice and
gives the option of adjusting timing in flight. I upgraded to the
SDS system and haven't looked back: easier starting, better fuel
economy, cleaner plugs, cheaper auto Iridiums, and adjustable
timing. Once setup it never needs adjusting. Hopefully much
longer life. The downside...needs battery power. I did keep one
mag.

Corbin, you will not regret putting in Lightspeed electronic ignitions once you get them working. Hang in there, you’ll get it.
You’ll be able to idle at 450 rpm which is good for landings on shorter runways and can run
faster higher up.
What’s Klaus offering in the way of help?

Terry,
Glad u
are happy with the SDS ... They have a good reputation ... Im currently
installing one on a Subaru . Apparently the latest Version ' 5' will
run Subaru Coils .. but the previous ''4' wont . I have the '4' .. and im
waiting for a 'patch' to arrive from Canada .. and when wired in i
should get adequate Spark .!
Then i have to establish the Timing
Settings somehow .. and find Knock Threshold .. and and .. !!
Cheers,
Graham
