Installed a PS3/2 board set into a Premier GP-40 (20-2425-1). All wiring is connected, no pinched wires. Tested the installation in conventional mode after the shell was installed and everything worked fine. Lights, sounds, horn, bell, couplers worked fine. Used the Technician service loader to upload the ps3 file and flash. Running in either DCS or conventional now and the rear headlight and interior lights do not come on. Tried feature reset - no change.
