Right Hand Ignition Coil Replacement.
Eldrick:
Last year I replaced the Left hand Ignition coil and that was easy. This year, I am replacing the Right Hand one (as you sit on the bike). I have a problem, the only coil I could find was ‘aftermarket’ and designed for fitting on either left or right side. This Coil does not look like either of my coils but it is described as for the CB400f.
Specifically, the issue I have is the wiring, the new coil has a Positive and a Negative terminal on it and it comes with a cable that has one Yellow and one Black wire. My right hand coil connects a Black&Yellow wire to Black and a Blue wire to Blue. The black one must be missing the normal connector as it has been soldered onto the Black&Yellow one.
I need to know which terminal (on the coil) to connect the nice new Black and the new Yellow wires to and then where to connect them vis-a-vis the Black wire and the Blue wire. As ever, pictures are more helpful, please see below.
