Filing Flight Plan
I have a problem that I have not been able to diagnose. When flying, any lights I have on will flicker along with the vacuum gauge, ammeter, and digital clock. With all lights and radios off, the flicker is present (indicated by the flickering ammeter. I pulled the alternator to have it tested and it is okay. All connections have been checked for breaks and looseness. Battery is good and connections are tight. The plane does not have a voltage regulator but it does have an ACU (Alternator Control Unit) that is in the J Box. The voltage varies from 28V down to 24 volts. Has anyone experienced this? Is it possible the ACU has gone bad? Any comments or suggestions are welcome.
