Hey guys, I hope my question isn't stupid! I made the entire harness for my little '27 Roadster, and everything seems to be working fine except the charging circuit. The car is running a little 302, and it used an external voltage regulator. I wired the regulator terminals correctly, but didn't use the "I" terminal, since I always assumed that is only for a charge indicator light on the dashboard. I just have the other three terminals properly hooked up (A to BAT, S to Stator, F to Field). Do I need to have the resistance of an indicator light connected to the terminal "I" on my regulator in order for proper charging, assuming all other parts and pieces are working and connected right? When I test the new alternator, it only raises the charging to about 12.6 volts, and that requires at least 1200 RPM's. Any help appreciated.
