Trimmed remaining wires and installed terminals for console LED warning, map switch, and USB. I couldn’t install the dimmer switch wires. Turns out I was shipped the wrong ones a year and a half ago. These are 5k pots I need 10k. Oh well will have to order more.
Drilled left mid cabin cover for pilot seat heat switch.
Began cutting wires to length, labeling and crimping connectors. Not a lot of room and my back is not happy. Have to take frequent breaks. Found three wires that are too short. Will have to rerun longer ones when I’m in the mood for a good challenge.
Ran remaining power wires from right gear tower to sub panel.
Fabricated GSU25 connectors.
I had a job in college fabricating the electronic assemblies that sense the metallic presence of a pay phone coin. So now it’s all coming back to me. Just wish I had one of those digital soldering irons!
Added click bonds to instrument sub panel, wing root ribs, and center bottom skins.
Ran wires from gear towers to instrument sub panel. Added labels and began cutting wires to proper lenght.
Work on 3/22-3/26/18.
Installed left wing root connectors. Combed and zip tied forward cockpit and gear tower wire harnesses.
Installed boost pump 1 and 2 wire connector. Glued connector mount base a remaining click bond.
Installed altenator to bus feed wire. Combed wire runs in both gear towers.
Match drilled baggage door micro switch to latch block holes and mount.
Primed and bolted parts together. Sanded baggage door latch rod for proper micro switch engagement.
Mounted SSC to base. I went with a 100 amp SSC instead of a relay or battery contactor due to the low on power draw of 6ma, over current trip, and low operating voltage. This will give me circuit protection as well as longer endurance on battery #2 power. Battery #1 will be used for engine start and therefore is controlled with a conventional B&C battery contactor.
Installed GSU mount bolts and adjusted unit to manual specs. The install manual requires that the connectors be aligned within 1°of either the longitudinal or lateral axis. Mounting to the sub panel should be sufficient.
Match drilled baggage shelf cover to stiffeners and installed nutplates on sub panel.
Mounted LRU’s to avionics shelf.
Installed a power-gate to shelf as well. Decided to go this route for two reasons:
1. I did not want a cross tie or an E bus alternate feed. I have two hot busses and Garmin dual feed avionics. Altenator feeds both batteries. This provides a simple solution with with over current and reverse current protection. If the altenator dies or a short the system splits in two due to the diode. Nice and easy, load shead and land. The cool part is I can turn off the battery’s and the engine will still run!
2. This is a mosfet gate so the forward voltage drop is around 0.2 V at 100 amps which is way beyond normal system draw. I am running lithium batteries and with a schottky diode the voltage drop will not allow full charging. Since I am running an electrically dependent engine this is a must.
