Have a 1978 CB750 with a dyna S ignition. Had no spark on the 2-3 stock coil so I installed new dyna coils with a resistor pack. When I timed the new coils the coils the 1-4 timed correctly but when I went to the 2-3 coil the timing light stays on all the time? Purchased a new set of dyna coils thinking I had burned a coil but still have the same problem. Checked all the wiring and connections multiple times. Any ideas or help on where to go from here
