Ugly Duckling

I pulled the flywheel and attached my meter neg cable to the ground and pos to both leads. The lead to the points shows continuity but the plug wire side is dead. I checked at the plug wire at the boot and where it emerges from the coil. Did I check it correctly?

Those coils were made before they figured out how to make them last only five years. It probably is ok. Remove the points and take them apart, degrease, then polish each contact shiny bright. Put it back together, set points to .020", and it probably will have spark.

Here you are only checking your plug wire and not the coil. The plug wire from the coil terminal to the spark plug connector should have almost 0 resistance. Just a few ohms. To check the coils secondary windings, connect your meter to the ground wire and the spark plug wire terminal on the coil. Depending on your meter, it will probably need to be set to the 20K range to test the coil and to the 200 range to test the plug wire. The coil reading should be in the low thousands.

I will clean everything up and check again.

I don’t know if I am confused or if I confused you guys with that. ^^^ I had my Neg clamp on the ground wire and checked for resistance with the pos lead at the boot first. Then, getting no reading, I also checked where the lead emerges from the coil so to confirm that it wasn’t just a bad spark plug wire.

Good stuff! Thanks.

I decided to revisit this little jewel. No spark. I pulled off the tank and the flywheel. I believe the coil is bad. What do I need to look for?

Just looking at the coil does not indicate if the coil is good, unless the covering is cracked and peeling.

Doug Penn did a nice job of explaining how to use a analog meter to test if the primary and and secondary windings of a coil are good.

This test is exactly what I have stated that I did to determine the coil was bad.
