  • Bad Coil? Plug Wires?

    Im working on my old bike, its now a friends, it's a 93 750 Katana. After the winter it wasnt starting so we checked spark and it had good spark on the 1 and 4 cylinders but the 2 and 3 cylinders there would be maybe one spark everyonce and awhile. So we swapped the coils around and we were able to get spark but then when we put them back 2 and 3 wouldnt spark again. We swapped them again and they didnt spark this time. Is it the coil or is there a bad connection between the pug wires and the coil.

    i don't remember if the wires from the coil to the CDI are removable. if so swap them & retest. it could also be a bad CDI.

    the service manual has a good test procedure on testing the CDI & coils.
