Just powered up my D-180 for the 1st time and it gave this error on the screen over the EFIS background. Also seemed to have a sound like an auto-reset breaker clicking on and off. Also I put in my Internal battery which is new, but been sitting a while., the Volt meter said 0 on that screen, but not sure if it is accurate since the internal service error message is on. Boy I was hoping this install would go well so I could wrap up my engine install...
