Kohler K141magneto test

[topconker]

Just inherited 2 Kohler K141 motors and hoping to get both running. The guy that let me have them stated there was no spark on the one I am currently playing with. I've removed the flywheel and see it has the later mageneto fitted and wonder if it is still working. How do I test the mageneto?

This manual should answer most of your questions. https://www.mymowerparts.com/pdf/Ko...al-K91-K141-K161-K181-K241-K301-K321-K341.pdf

Thanks Rivets, I have that manual but can't see any specs in there for the magneto

 

[topconker]

Ive used a multimeter to check the mag which gave me a reading of 4.85K but no idea if this is way below spec or is ok. Want to check before I rebuild.

 

[Rivets]

I like to have primary resistance (small wire to ground) below 15 ohms and secondary resistance (spark plug wire to ground) 12K-15K ohms.

 

[topconker]

Ah, well that looks like the mag is no good then

 

[Rivets]

Are you checking with the mag installed or off the unit? Second question, did you disconnect the primary wire from the points and condenser before checking if it is installed?

 

[topconker]

Off the unit

 

[Rivets]

Ok, then I would agree that the coil may be bad.

yep, they seem a reasonable price and will fit electronic ignition at the same time.
