Opinions please

"Everything" is not a word that computes. You have to be specific. I cannot tell what you are doing

1...Make sure the meter works. Check the battery voltage.
2...Is there anything supplied by the ignition switch that does not appear to work? That would be a clue
3....Do you have a 2 or 4 wire ballast resistor? If you have a 4 wire, there should be one end with both terminals jumpered together. That comes from the ignition switch in "run". Hook your meter to that, put the key in the "run" position and see what you have

4....Double check the above by checking the blue wire feeding the alternator field. With the key in "run" it should be very close to "same as battery."

5...It is IMPORTANT to understand that the circuit CHANGES between "run" and "start" positions of the key. The test in (4) only works in 'run'. The 'run' voltage GOES DEAD when you twist the key to "start"

Hook the meter to coil positive, and twist the key to "start." You should have at least 10--10.5V or more
