Re-installed the AV-50001 Power & Switch Module and the harnesses. Used a multimeter to check continuity (short) and there is a short in the Nav/Strobe fuse location. Tried a fuse tester that I got from Harbor Freight and the in-line fuse blew immediately when I turn the Nav/Strobe switch ON. I checked continuity of the pins in all the harnessed that connect to the AV-50000A Control Module and all the pins in the Control Module. I found continuity in several pins but I need to review the electrical schematic to see what the wires are for. Verified that the 3 wires (BRN, RED, WHT/YEL) from the SV AP-Knob Harness are correctly inserted in the 25-pin D-sub connector of the WH-00031 Switch Module Harness, and they are.
