With regards to AMM and WDM pages I have just emailed:
1-what is D7276&D7306/D7304/D7308 and D7274/D7284/D7282/D7286 in the WDM33-51-14?
2-What does STA 727E for Aisle Light and STA 727D+6 for over wing escape light mean?
3-With regard to AMM33-51-02 trouble shooting, replacement of the inverter, have you found any replacement procedure in the system schematic manual?
"STA" numbers are longitudinal distances from nose. Reference ATA Chapter 6.
Inverters make alternating current from direct current. Your aircraft emergency lights must use A/C for some reason (I have never seen A/C emergency lights).
As far as procedure of replacement, that should be in your Maintenance Manual.
