Toro 524 electrical

My Toro stopped and had no spark after.
Removed flywheel and check condenser points gap, .025. Set to .02 and cleaned
Ohmeter from HT to coil block was open. Cut an inch off and reattached to spark plug boot and now have 7.3K ohms.
Still no spark (checked plug seems ok with ohm meter)
What should the readings be on the ignition coil primary and HT?

This is the only info I could find about Tecumseh coils.


Is the kill wire disconnected? Could be grounded?

Check to see if the Flywheel magnets are intact, and in the correct position.

It is an older unit . The points and coil are under the fly wheel. The magnets are in place. I disconnected the ground wire where the throttle grounds out when slowed down, Anyone know how to evaluate the condenser itself?


If the coil was outside of the flywheel, I would have put an electronic ignition in. I will buy the parts I need but want to make sure it is not a wiring problem. I'll look into the other modules

Interesting readings you attached. I'll have to check mine again.

Thanks

I bet your points are corroded/pitted; you're not going to get a spark with bad points.

I've had good luck removing them and sanding them until the pits are gone and the faces are completely shiny & uniform.

be sure to not rotate the magneto...if you do, you'll have to reset the spark advance; that's "fun".

As stated above, Clean the points, or replace them. Replace the Condenser, Condensers are Cheap. Breakerless modules are fairly cheap as well. https://www.mfgsupply.com/31-8786.html

Thanks guys, been too cold to work on it. But I did clean the points and when they make contact i was getting a continuity reading with my meter. I read some of those newer modules don't last not sure. I'll check it out when the weather gets a little warmer.
