Question
How do you confirm your electronic ignition is working?

I have a DLE 30 engine that has never been run before that I installed on a Factor 30 cc plane and I've been having some problem trying to start. I'm not 100% sure I have all the electrical set up and working properly. To see if spark is getting to the plug, can I remove the plug, ground it to the engine, and flip the prop and watch for spark? I do this basic procedure with other small magneto gas engines, but I don't know if this could damage an electronic ignition this way.
Thanks
Lamar

Yes you can install a plug into the ignition and flip the prop. It don't need to be ground to the engine to fire

Correct but you have to flip it fairly hard. There is a minimum speed the ignition requires to fire.

As long as the spark plug is installed in the cap you will not damage the ignition. It does not need to be grounded - it already is. A spark will indicate the ignition is working, but not if it is working correctly. Your best bet would be to try another ignition (Rcxel, RcXP, etc.) that you know works properly and see if it resolves the problem.

I was waiting for someone to come up with that answer.

Trucker are you sure it is getting fuel. Lots of time on a new DLE the diaphragm is dry and you have to lossen the big screw in the middle to break the airlock loose to get fuel to the rest of the carb.---Smitty

That's a good point...the OP did say it was a never ran engine...not getting that first tase of fuel is a real good chance

Not every engine is like this. On my DLE 55 I just have to rock the prop back and forward over the sensor and it will spark.

Correct. All DLE's will fire with a prop rock back and forth. On the other hand my DA engines need to rotate fast for the ignition to fire.

There will be no doubt this way if there is a spark.

More recent production RCexl ignitions as used by DLE and many other companies require a faster prop flip to spark than older ones. The original version A-01 will spark at any speed.

Wonder why they went away from being able to just rock the crankshaft to get a spark.--Smitty

So that you need to buy more equipment to set the timing
