Hi MiP
actually the REC's are not like on the older systems
there is one large square one underneath the spider block assy, this is the #1 REC, then beside that are 2 smaller ones which are the #2 and #5 REC's.
Those silver diodes with pigtails you see are the #3 and #4 REC's.
If you want a panel schematic you can go to flight systems website and lookup the GE EV100LX manuals and they have all the information you need to identify and check these parts.
www. fsip. biz (remove the spaces i added to this url to make it work, or you can google fsip.biz and it should come up as the first hit. Go to the support pages and you can find technical manuals there for that panel.
