That pretty well eliminates the kill switch and every other thing in the power ciruit, and means the problem is between the coils and the points.
To verify that, take the points cover off and turn the crank (use the big nut on the end of the crank (15mm I think) NOT the small nut) untill one set of points is closed, then check the voltage at the negative (points wire) side of both coils with the key on. If you have 10-12 volts at both coils on the negative side, then there is no connection between the negative side of the coils and ground (through the points).
Point connected to green wire (right side (or front)) closed:
Voltage black wire (coil 1,4): 10V
Voltage green wire (coil 2,3): 3.7V
Point connected to black wire (left side (or rear)) closed:
Voltage black wire (coil 1,4): 3.1V
Voltage green wire (coil 2,3): 9.9V
I'm not sure to understand if your last sentence means I should or should NOT get a connection between the neg. side of the coils and ground ?
Simpler to just measure the resistance between the negative side of each coil and the wire where it connects to the points though,
I got 0 ohm for each connection
then measure the resistance from the wire where it connects to the points and ground (with the points closed). With the key off both ways.
Now the results become interesting:
Point located at the right side (or front) CLOSED:
wire that connects to point to ground: 1.1 ohm
wire that connects to other point (opened) to ground: 0.0 ohm
Point located at the left side (or rear) CLOSED:
wire that connects to point to ground: 6.2 ohm
wire that connects to other point (opened) to ground: 6.2 ohm
And then I realized that the gap of the point located at the right side (front) was less (.006) than the other (.012). What should be the correct gap ?
Is that why there is that much resistance with the right side point even if it is opened ? Should I have 0 ohm when opened, as I have on the left side point ?
also, I guess it is normal that the point that is closed when the key is turned on gets quite hot ?
