Set up in the controller overlap screen you choose which phase the overlap operates permissive and which phase operates protected. The protected phases are your standard left turn phases 1 3 5 and 7.
The green arrow for the doghouse is the green output on phases 1 3 5 or 7.. Same as the the crossing street left turn green arrows. The yellow arrow on the doghouse is the yellow output on phases 1 3 5 or 7
The red arrow, solid yellow arrow, and flashing yellow arrow are outputted on the overlap channels as red yellow and flashing green. In the cabinet is switchpacks 13 thru 16.
So, then the doghouse are wired correctly (Green and SOLID Yellow arrows) and it is a program problem that will never be corrected!!!
The right turn doghouse arrows need to be overlaps "E", "F" "G" and "H" to work correctly.
The right turn arrows are normally tied to the left turn protected movement switch packs. Which in a standard 8 phase cabinet are switches 1,3,5,7 for each approach. Red on those switches are not used, yellow is for right turn doghouse only, green is for both right turn doghouse and cross street left turn 4-section FYA head
I think I know the problem now. The yellow arrow is tied into the THRU phase for the cross street. The setup looks to lead with a left turn green arrow, and green ball all on for one direction (with the right turn green arrow on the doghouse). When the cross street left turn switches to solid yellow the doghouse goes dark because the yellow right turn arrow is wired to the cross street yellow thru switchpack, not the proper odd-numbered protected turn movement switch pack. At the end of the cycle when the thru signals turn yellow the arrow comes back on.
That would make more sense actually
