H4 mag

I have farmall super H.
Mostly, restoration of engine was finished.
But,dose not spark.I changed new point,rotor,and cap .
But,dose not spark.
I think that it is a thing with bad Coil,or poor contact.
Please let me know!!

If there's no spark remove the coil cover and use a flat blade screwdriver to touch the magnets near the coil. They should pull the screwdriver with some effort. These are what generates spark in a mag when passing past the coil. If the magnets are ok, I think your coil may be weak.

Thanks a lot,

Is it a mag that previously worked on that engine?

Have you verified that the mag is actually rotating with the engine?

When the mag is installed on the engine, is the "kill" wire connected to the mag?

Thanks,H4 mag is genuine for super H.
This tractor is my grand father's
After he stops operating, about ten years have passed. tractor is still in the state at that time.However, wiring had run out.
I have tried to restore for him who passed away.
