No spark

Many thanks

I did check that the spring was in good contact with the points.

If you have 9 volts at the top of the coil (front mount dist) then that is about right - for a 12 volt coil. Since coils are not marked at the factory and it sounds like someone else did the conversion, you probably don't know what you have.
There are ways to find out if the coil is 12 volts or 6 volts - check the recent archives for the procedure.

Not sure why you think the coil is fried other than the voltage reading. Is the little spring on the underside stretched out enough to contact the dist?

The simplest thing to do would be to get a new 12 volt, front mount coil and make sure the resistance is right by measuring the voltage at the top of the coil - it should be battery voltage with points open and between 8 and 10.5 volts with points closed. Some folks claim less or more volts is OK but in between those readings and you can't go wrong.

And you should see Dell's posts on the proper resistors to use - don't use the original resistor with the 12 volt coil - do use the original resistor along with a 12 to 6 volt droping resistor with the 6 volt coil.

My 6v front mount coil reads 0.6 and 6.97k respectively.
