Ignition question

[1966satellite]

My brother has a MSD distributor on his 440. He is currently getting spark from his distributor but none to the spark plugs. Does anyone have any idea what the problem could be? It was working fine last summer.

Did he put his rotor button in the cap? I would expect either missing rotor button or its badly damaged.

Could be a weak coil if not a rotor problem.
Is the spark blue/white and crisp?
If it's yellow and lazy then you have a component problem.

Thanks guys! I'm betting it's the rotor button. He's getting a strong spark from the coil.
