Electrical Issue on 1970 Chevelle

[lovemius]

When I conducted a power check on both of these terminals, I only had power to the clear one. Am I missing something? I can't get my car to start. New ignition, ignition switch, voltage regulator, horn relay, and alternator, what do you think the issue is? Please help, I want to drive my chevelle at least once before I go on deployment!
