There is a contact inside the solenoid that powers the "I" terminal with full battery voltage when the solenoid is engaged.

Then, when the solenoid drops out, the coil receives reduced voltage through the ballast circuit.
Never knew! Thanks..For some reason I thought the ballast took care of all of that.
