Dealing with light matrix problems, using a logic probe - Gottlieb Raven Sys80b - Part 1/2

Work continues on this Gottlieb System 80b pinball machine Raven, but there's a problem with the light matrix. Certain lights are not properly activating. I go through the process of fixing some lights that aren't working properly. This video chronicles the entire process of diagnosing what the problem is. I go over the schematics and how to use a logic probe to test the circuit.
