Alternator+Battery Misbehavior...
...
Started up the aircraft this morning and observed the usual & expected high current ( ~60A) indicating that the alternator was recharging the EarthX ETX 900 after its usual vigorous spinning of my IO-360-A1B6.
Taxi'd out to the run up area, glanced at the AMPs again, and WT*?!?! still showing 55A at 900RPM...That's not right...
Long story longer - taxi'd back to hangar and proceeded to un-cowl, inspect, uninstall Plane Power 99-1012 60A alternator. I replaced the regulator/field brush assembly with a spare (from the first Plane Power alternator failure 2 years ago.). Ran up, and observed normal/expected behavior, put everything back together.
So, I ordered a B&C LX60 + LR-3D regulator and will do the replacement/conversion when I do the next oil change...
I cannot have critical components with a MTBF of < 100 hours.
