Starter wiring....... "S" terminal is the energizer wire to engage the soleniod and make the starter motor spin. The "I" terminal is the "hot in start" wire that provides a full 12v to the coil with the old points system and is not needed with an HEI dizzy. The old wire to the points dizzy only had 9ish volts going to it when the key was in the run position, you need to make sure that wire has a full 12 volts in run and start positions. If it has 9ish volts you need to run a new wire from the dizzy to where the old resistance wire hooked into the ing switch and do away with the old resistance wire. If the new wire isn't providing 12v when the key is in the crank position..... simply route the wire from the "I" terminal on the starter and splice it in at the dizzy. BTW never heard of a wire from the starter going to the voltmeter or idiot light..... unless it was connected to the large battery feed terminal
