The kill wire from headlight switch has been removed. The points have a continuance either open or closed.
When the wire from the magneto coil is removed from the points the points will then make and break.
When the wire from the coil is tested with an ohmmeter it shows a continuance with the frame, should this be right or is it shorted? Could the condenser be bad?

This bike has been in storage for years but it has never gotten wet, always dry. Can someone please help?
Thanks. Frank

Moved your post

It seems more appropriate to put it in with the Vintage area.

A friend had a problem with no spark on his /2. I came over to try to help diagnose it. He had managed to put together all the wires on the little screw that attaches to the points incorrectly and it was always grounded. It sounds to me like you have a problem at the points if they never break from ground.

You should only see a few ohms of resistance between the coil wire to the points and the frame. If you measured continuity with the 1k Ohms scale, you probably wouldn't notice it.

If the condenser is bad, typically the bike will start and idle, but won't rev and will instead spit and miss and backfire. I guess a condenser could fail as a dead short and then you'd see your symptoms, but it hasn't happened to me.

BMW R60 no spark

Thanks so much for your return. I removed the coil from the bike and I am getting a full scale on the ohmmeter when I test the coil wire to the metal core of the coil. With the coil out of the circuit the points will open and close the circuit on the ohmmeter. Thanks Frank
