Dear Sean,

I don’t think that 50 ohms should play the continuity sound, that is a substantial resistance compared to short.

Your ac and bc readings are what seems to be substantially different than mine although not that much different than each other. I bought a used working set  stator and rotor, when I get them I’ll remeasure and post my results.

Till then if someone can post their results that would be great.

I’m on the hunt for parts at the moment but I’m kinda low on budget so I hope I can get a complete spare electric system at a  not so steep price. Then I’ll be able to replace parts and see which part is faulty. Till then I’m with the tools I already own and good advice from knowledgeable forum members.

Any way to buy only rotor without the stator?

I’m very happy for you Norm. Happy and safe racing.

Norm,

If you did the “strike test” and it sparked, then you have either a power box issue or a defective stator. A wiring problem could also explain those symptom. If you have a DVM you may measure the resistance of your stator and use the values I got as a reference to compare to the measurements you take despite you having a slightly different stator. Actually you have two stators so you can compare one to another unless both are bad. Also measure the voltage on the wire going into the coil while pressing the start button and see what you get. Write the results here and we’ll take it from there.

Dear Tony,

When I took out the stator, I did see a few scratches on the stator that looked suspicious to me that were made from the rotor. How does that influence spark creation?

I will check later today if I have any kind of movement in the crank bearings and let you know.

You have the exact problem as me? Meaning your starter turns but you get no spark? If so you must do the “strike test” I did, that means you take out the plug, take an electric wire, at one end you connect it instead of the wire going into the coil and on the other end you strike the positive pole of the battery while someone else is watching the plug to see if there is a spark.

Don’t make a connection to the positive pole of the battery for more than a brief moment!! Only strike it like you try to light a match on it. Leave the ground wire going into the negative pole of the battery connected.

Let me know the result…

Do you have spare parts for the pre 09 leopard?

Do you have parts for the Leopard?

Thank you for following up on my logic in this troubleshooting, it always helps to have someone else look at what I’m doing but from their own perspective.

I’m originally a motorcycle mechanic, I was really surprised to see IAME not publishing the resistance values of the stator. Measuring resistance is a very simple and common way to determine if the stator is in good working condition or not. Shame… Hope someone with a good working stator can measure so I may compare the values.

No, it wasn’t wet. I don’t see how this is relevant though, we have one situation that we have a good spark via the small test I did and another situation were we don’t have spark at all, that’s when I press the start button. The difference between the two situations, if you take the battery out of the equation (I checked with three batteries) is the stator and the power pack. Fuel has nothing to do with it, That’s why I asked for the resistance measurements of the stator that would let me know if it’s the stator’s fault or the power box.

ThanX

I painted the wiring diagram and all the measurements I took:

I hope it’s clear…
Thank’s
