OK guys.....need some opinions. After my son and I flew our RVG6A to KDYB and back last Friday we noticed the GI 106A seemed inop. I have it slaved to the SL 30 only and we could hear the identifiers but could get no needle deflection. When changing nav freqs, the cdi seemed to switch positions. Also the nav/loc light is illuminated all the time. We could turn the OBS and that had no effect whatsoever. Where to start troubleshooting?
