Hi Guys,
I hope somebody can help.
I have a very nice JD 317, with a Kohler KT17 engine, it appears that the coil is not working.
I can't find a replacement.
Could anybody recommend a replacement coil and condenser?
Best regards

I went to a Kohler dealer for mine. They are not cheap. I think it was close to 100 dollars for it.
Other than that ,you could post in the want ads here ,or keep checking Ebay out.
What makes you think its bad. Have you tested it out ?

Yes do points and condenser first they are available from any Kohler dealer and are not expensive. There is a twin tower coil for early 12 volt Harley motorcycles that will work, be sure you get the true 12 volt coil and not the 6 volt coil that requires a ballast resistor, found one on line for about $38.

Fred,
If you have a voltmeter/ohmmeter, you can check the coil. With the wires removed, the resistance across the primary posts will be about 4.5 ohms. The resistance between the two secondary ignition wire connections on the coil should be 10 kilohms (10,000 ohms), give or take maybe a thousand ohms. There should be no continuity between primary and secondary. Typically a bad coil has the secondary connections open.

Thank you all for the information.
I really enjoy the site ( new to it )
The points are good, however< I have no confidence in the condenser & Coil
With the key in the on position, the coil gets hot to touch.
There is 12 volts on the in, and "0" volts on the out to the points.
I will check with a Harley dealer.
The JD dealer here wants $ 226 for the coil & condenser.
All the best

Check the voltage on the "- "coil terminal(out to points), should be 12.5 when points are open and 0 volts when points are closed. If it is 0 all the time you have a short somewhere in this circuit.

The condenser should Ohm OPEN when disconnected from the system.
