So I recently upgraded up my dizzy to a Mallory comp 9K and its running off a Promaster coil.
Yesterday I was testing spark and I have none! Battery is fully charged i verified with a multimeter voltage going in to the coil. I tested the out put with a spark plug and I am getting spark from the output of the coil, But no spark at the plugs them self's. Rotor is in good shape.
Any one have any suggestions or things to check?
