But yes, the rest of the system is unchanged. Dash warning lights still operate, no change to POH, etc.

I’m currently in a tech discussion over email with plane power folks on this very issue. The instructions say all the original circuit gadgetry is removed when R1224s go in. That includes the ALT restart circuit. Ultimately, new POH procedures are needed via supplement.
The R1224 appears on certain PMA paperwork, but no STC is published for the 337 type A6CE.
I’m also chasing ghosts and will be rebuilding the original circuit board And diodes this week.
