No spark on plugs 2 and 3 with dyna s

Hi I just purchased a 78 kz650b the bike was running fine until one day I tried to start it up and nothing. I checked for spark and the plugs for 2 and 3 have no spark. I swapped out the coils for new ones and I'm still having the same problems. Could it be the dyna have failed?In the pic the wires on the right side for 2-3 (red and black) both have current is that correct? Any help would be appreciated.

hey guy i had my one side of my dyna fail on me this year ..replaced coils wires that i did not have to until i found the problem.swap the primary wires on the coils and see if the problem moves to 1 and 4 ..dynas are good but they do go sooner or later...
make sure your connections are nice and tight...look at my past discussions under my profile..the guys here got me up and running

Red is the +12Vdc to the Dyna pickups....
Black conductor is the pickup feed to the coil for 2 & 3 cylinders.
