I'd check continuity through the fuses using the pins on the connector. With these DE boards, that corner is basically just a fuse hub. Power for the GI cimes in on one end of that connector goes through its corresponding fuse and then exits the other end of the connector. Pretty easy to follow the traces on the board. Check for beeps from the start pin, through the fuse, to the exit pin on each of those traces. The DE fuse holders were junk, possible issue there. Best of luck.
