Background info. This is an RV12 with 912uls. Recently had an electrical problem with the power board. Capacitor failed and let out the smoke. Replaced the capacitor and thought that would be good. Since then I'm getting intermittent errors on the AP74. Sometimes it will come on and all the lights will be on and not go out. I get AP errors on the EFIS, AP/err/err I think it is. I've opened it back up and reseated all the connectors to make it it wasn't just a loose connection. As it sits right now I can turn on the AP74 and the Heading and Alt lights will light up. The track and nav lights are inop. I'm thinking during the time that the board was out for repair that maybe I've lost some configuration files and the D180 is no longer seeing the 496. Reading the manual I'm a little unsure if I can access the menu to see whats actually talking to the 180 without going through the entire reconfiguration. Any help or hints would help. Plane flies fine but we are planning a long trip and the AP would be nice to have.
Thanks Rick
