What should coil and ballast resistor voltage be?

I did some voltage testing at the column switch harness connector. I was getting 9.7V to the brown wire when cranking. I then tested the red power wire going into the connector and only get 9.9V cranking. Battery is over 12.5V. The engine harness is new. Perhaps I need to pull the bulkhead connector and see what is going on with the power connector wire (terminal J according to the diagram). I'll test power into the bulkhead at the blue wire first to make sure there is no issue on the engine side.
