I have been looking at Ken H's wiring diagram. Someone is going to have to explain to me how the starter solenoid / relay works as shown. I see 2 coils labeled only as K It seems to me that the lower (right) coil would be energized by K1 and in turn would close the K contact to power the starter.

What confuses me is the other K coil (wired vertically in the diagram). It appears to me when voltage to the K solenoid from k1 is dropped, then the to two solenoid K coils are now in series with +12 and power is being applied by the closed K N/O contact. If this is true, we would have some voltage other than +12 or 0 at the K1 N/0 contact that he is reading.

What am I missing here?

Do we have a diode missing in the diagram?

Is the diagram wrong?
