you can also test from the board, put the pin in test mode and compare the three with a DMM, connector (Red Light) J133-4 is red/orange wire, (Yellow Light) J133-5 is red/yellow wire, (Green Light) J133-6 is red/green wire...

Quoted from cody_chunn:On circuit board twist sockets, reflow header pins and twist-in crescents at the socket. Those little black divots at the end of the silver crescent shouldn't be there.
Move the non-working socket to a working location. If it blinks, the socket and lamp are good.
I'm going with cracked header pins if the board has a connector.
Putting my money on ""reflow header pins", I just had to do that on my upper red, yellow, green targets...

When you look at the Supercharger in test mode do the Opto's show "closed" or "bad"? Are you able to enable them?
Definitely need to confirm status, normal condition would be closed. What happens in switch edge test mode, basically break the beam between the opto's and see if the switch reacts. I'd check the one where the bad enters the ramp and all three opto's in the SC. The ramp and SC and controlled by two different boards, are they the only ones that are not functioning. Looking to see what the common factor could be. Both of those are fed from J-206-9 column 8 along with several others, if the others are working then Column 8 is not the problem, IMO.
