I'm considering dual PlanePower R1224s regulators. Looks like replacing the regulators with the R1224s eliminates the irksome diode assembly and alternator sensing circuit boards, and the overvolt sensor.
Plus side: solid state parallel load sharing & regulation & sensing in a fairly inexpensive unit (about $220 ea @ qaa.com). Appears the current annunciators for FRONT and REAR alt out can be used. Also likely eliminates the battery pack (so overvolt button and ALT reset button could be re-purposed for chem trails
)
Downside: Might require STC (still researching approved models), certainly requires 337. If one goes offline, it stays offline and you finish the flight on 1 alternator. If both go offline, you finish the flight on battery.
Annual coming up this winter...if I can't get my circuit board and diodes all squared away, I might just rip it all out and put in the planepower regulators.
Someone also on this board re-build the circuit board & diode assy--might try that first--keeps the paperwork to a minimum.
