Fuselage Wiring: 2.0 hours

Installed altenator to bus feed wire. Combed wire runs in both gear towers.


Miscellaneous avionics: 5.6 hours

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.
