Today I continued with more wiring. I finished the SD-8 ammeter wiring that I started yesterday, and made a cable for the starter:
I found a covered fuse block to use for the battery bus. Since it is on the engine side of the firewall I was worried about an uncovered block getting dirty. The only thing I don’t like about it is that each fuse feeds separately. To fix this I bent all of the tabs on one side:
Then I cut a piece of brass into a 1/4 inch strip and rounded the corners a little:
I soldered the brass piece to the bent tabs, very carefully. I was able to get good melting without any of the plastic housing.
Next I started working on the P-leads for the mags. These bendix mags use a special terminal end.
New kits are available to build the p-leads, but since I have these old ones I’ll just use the parts to make mine. The far right side is a soldered end that includes a small washer. I was able to melt the solder and extract the washer from the old ends. I used shielded wire and connected the shield to a ring terminal and grounded it on one of the screws on the back of the mag housing.
I’ve also been working on the wire conduit in the wing. I cut a notch to allow entry for the Dynon magnetometer cable, but that made a weak spot in the conduit tube. I cut a piece of aluminum tube for reinforcements:
I added rubber grommets to each of the holes in the wing ribs, then reinstalled the conduit.
