This is asking about a 1975 CB750K
I just got my new electric ignition and dyna dual output 3 ohm coils.
As you can see in this first picture, there were no coils or spark plug wires when i bought the bike.
I am having trouble figuring out how to wire it. The dyna wire instructions and the Clymer manual assume you are replacing coils, not starting from scratch.
The second picture shows the wiring harness wires that need to be connected.
Do any of you know what each of the wires are? Can you tell me which wires to connect to the coils?
The wires in the second photo are, from left to right, Yellow, Blue, Black/White, Green, Black.
The Honda manual says to connect the yellow, blue, and Black White leads to the wiring harness. The dyna coils have 2 connection points on each coil.
Also, the second picture shows 5 wires and there are only 4 connection points??
Finally, someone told me not to forget to ground the coils. As you can see there is no mounting bracket with the bike. I will have something fabricated once I tear this bike down, but for now I need to temporarily mount them so I can make sure she runs. If I use hose clamps to mount the coils, do i just need to connect a wire from either side of the coil to the frame somewhere? Or do i need to ground both sides of the coil?
