Tony,
Thanks for this. Two questions:
1. Is D-Sub pin 13 now an open unused pin, or would the new fuse wire share that pin with another wire that's already attached?
2. In your photo, it looks as though the Ignition Harness is routed through a black tube, just below the red shrink wrap, and that the black tube is much narrower than the D-Sub. If so, how would I get the Harness out of the plane and then back in again. Or is the "tube" actually part of the D-Sub itself, so that once I get access to it, I'll be able to take it out without passing it through anything?
1. Pin 13 is a used pin. It is the connection that carries the voltage from the 1 amp fuse (that burned out) to the Master Switch. When the master is ON that voltage then goes out through Pin 14 to the VR sense wire. Pin 13 has a white/yellow wire. The new fuse wire could be spliced to that wire and the D-Sub's at either end of the harness would not need to be disassembled.
If I were doing this I would disconnect the battery first. Use a ohmmeter to check continuity from the new fuse wire to pin 13 and also pin 13 to pin 13 on each end of the harness. The pin numbers can be read on the end of the connector but they are really small. Be careful reinstalling D-Subs so as to not bend any pins.
2. There is no black tube, just a D-Sub connector at each end of the short WH-00030 harness. The red shrink wrap just goes into the D-Sub.
P.S. If you are new to this it would be good to review Section 5-21 (Electrical) of the KAI which is downloadable from Van's website.
