The "I" on the solenoid is a 12 volt bypass that connects to the ignition coil on the original application of your solenoid. Full 12 volts goes to the coil during starting of the engine. When you let go of the starting switch the coil voltage drops to around 6 volts because of either resistor wire or a ceramic resistor in the ignition circuit. You shouldn't need to connect the "I" post on the solenoid in your application. Good luck with your project. Bob
