Working on a 1987 C30 Truck. Having issues getting switched power from the "IGM" on the fuse box. We lost power to that port and that also must be the field wire for the alternator and gauge lights. I backfeed power back into that port and alternator and gauge lights work. It must just be a tap as it does not have an area where a fuse will push into. Wondering if this is protected by a fuse/Relay or fusible link. It is located on bottom left corner just above where fusebox screw is located. Thanks for any help!!

I would check the fusible links first, should be 2 on the starter and one or two on the firewall terminal.
