Hey guys, I got an 82 cb750 nighthawk. I can't figure why it has no spark. The problem I'm having now is that one of the coils seems to have constant power and buzzes. I'm wondering if this bike had points as there is an electronic pickup unit in it but not sure if its stock. Any help appreciated, thanks
 
Electronic was standard on them. Both coils get constant power on the plus side (black) but it should not be grounded on the minus side (blue or yellow).
 
I was about to post about a rough running and generally lack of idle on my bike (a 1979 CB750K UK bike) and I saw this post.
I believe my wiring may have been swapped on my coils as my +ve connections are the yellow and blue cables, could this be my issue??
New post started so as not to hijack sorry.
