I have a Plane Power 60 amp alternator (and back-up Plane Power 30 amp alternator) with a Advanced Quick Panel System. Here is east has been going on.... 1. My primary alternator never get adequate charge. It hovers around 12.5 to 12.8 volts, sometimes to 13.2 or so, but never above 14 volts. 2. The primary alternator makes an whine when on. 3. The primary alternator shuts off intermittently (I see Amps of down and whine goes off) and then will come back on on its own later or sometimes will when I reset field switch. 4. I can sometimes get full charge (14.2) on ground with only some of avionics on (one EFIS, nav/strobes only). 5. My secondary alternator does not do all this. It works indicated. Here is what I have tried and checked... 1. Checked and adjusted belt tension on alternator. 2. Added alternator filter. 3. Checked continuity and tightness on all connections. 4. Changed and checked alternator ANL fuse. 5. Got completely new alternator and replaced it. 6. Changed terminal plug on alternator. 7. Been on phone with plane power numerous times and ruined through trouble shooting and can't seem to find and issue with alternator itself. 8. Have not had alternator checked but since I have two alternators doing same thing and both are basically new, I doubt that is the case, but possible. 9. Volt reading on EFIS and multimeter at AFS middle same and same on both EFISs Any thoughts on what else to check or fix. I feel like I am missing something obvious. The plane with run with with the 12.8 or so volts but that is not what it should be. Could it be AFS module (they don't thing so at AFS), battery, do I need larger gauge wire (I have 8 now). I just don't know know anymore and and stuck on my true amateur status.
