1967 - 1969 barracuda Instrument Cluster Lights Out

Used everyones advice: checked the bulbs; incoming power from the orange wires, cleaned the bulb socket housings; bench tested the circuit board; installed dedicated ground wire from circuit board to frame; replaced bulb sockets and...... it works I have lights. Thanks again for your help!!! The car goes to my mechanic next week for final tuning, then off to the detailer for wet sanding / polishing and then put the shiny bits on and ready for Spring/Summer. Final pics to be uploaded.
