Voltage at the "I" wire is from the ignition switch that tells the regulator to start working. with the old mechanical, the "I" voltage was used to provide the initial field current so when the alternator spins it will make current and become self substaining. (it sometimes possible without "I" to race the engine and residual magnatism in the field get the alternator/regulator working.

the resistor around the indicator bulb is to provide a path of current to the "I" terminal in case the bulb is out. If you don't have voltage at "I" when ignition switched on, you could make a monetary jumper to "I" while spinning to flash the field and get it working. (or even use a toggle to provide "I")

BTW, did you go to the autocross?
