This is the wiring diagram for my engine, except I don't have a generator or regulator.
I've wired & re-wired this 2x now (new wires, new harness, new everything). Everything works great, and I have a perfect spark on each cylinder. Electric start is flawless. Electric choke pulls in nicely.
But I have one problem I simply cannot figure: the ignition kill switch ties the points together, thereby connecting both to ground (inasmuch as one point is grounded at any given moment), and my DMM shows me that all wiring is correct. Except, when "kill" is engaged, only the bottom cylinder goes dark. The top cylinder continues to spark. Every wire is landed correctly on the vacuum switch.
Not to brag (not my purpose or point)...but I'm an EE with a strong background in practical wiring. I understand this wiring diagram completely, and I've checked everything over & over. When the "kill" is engaged, my meter says the points are grounded....yet when I crank the engine, I have a bright blue spark on the top.
What am I missing? Any ideas?
