So so helpful. Took notes and added them to my phone so I can reference when I work on one. About to work on the Wico on my JD H. Weak spark.

Great video-you have de-mystified the magneto! Thanks for providing ohm and farad ranges. And…nice to see your mag tester machine again!
@jonelsonster2 жыл бұрын
Yeah, I'm always messing around with magnetos. They really aren't too complicated. Checking condition of condensers and coils before you replace them is nice... Then you're not just spending money on new parts when they may not even be bad. And that tester is so useful for making sure the mag works before you put it back onto the tractor or troubleshooting bad spark.

No doubt you have that figured out on how they destroyed that Ground connection. When people work on things who don't seem to have a clue how they operate. As for me, you have let me know what Wico Mag we had back on the farm. I had commented in another video of our JD's that had 2 different looking Wico mags. I had said that one was temperamental depending on how bad it rained. The one that never had a problem had a cover that looked like this one. The other one was different but whether it was a gasket problem? So long ago now BUT would expect one to know if it was just that. All i recall is if it had rained hard and it wouldn't start, take the cover off, you would see moisture in the cap. Wipe it out and then it would start, of course. At least i think the other was Wico too. Assume JD just had Wico's? Way back in the early 60's to mid 70's for me and i sure don't have the memory my Dad had!!

This is a Wico X. They are a good mag. The Wico C is a little older and has a different cap. I wouldn't be surprised if the one you had issued with was a C. But Deere also used Fairbanks Morse and Splitdort too. Not often, but sometimes.

Dads 54 JD H had two mags that came with it one like that and one that had a rounded off set cap also a Wico mag. Both were self sustaining although his H had a generator and electric lights and a eletric starter we couldnt keep batteries in it as resident hippy rastafarian types would boost them to sell or use them in their ford pinto. Which only barely started it with 6volts. So haveing a magneto was a good thing

I really like the simplicity of an engine with a magneto. It's nice being able to start the engine without a battery.

I am working on my own Wico X magneto from my 1941 John Deere model A. I am getting no spark from the magneto. I tested the primary coil and have 6.5 ohms, is that bad ? You state that there should be 1.2 ohms on the primary coil, and between 6 and 8k ohms on the secondary. I have 7k on mine. I am assuming that with the higher resistance that there is some problem with the primary. The center core was also a little rusty so I have taken it out and cleaned it.

I don’t have a comment I have a question, why does the nut on the back of my wico x mag keep coming loose
@jonelsonster Жыл бұрын
Sometimes there is a captive washer that prohibits the nut from being able to turn. Sometimes it's missing. If this is the case, red loctite can help prevent the but from backing off. But it also makes future disassembly a bear.

There owner of this magneto hooked the battery up to the kill switch... So either 6 or 12 volts was shooting through the kill switch strap, which burned through it in a hurry.
