Music: Fleetwood Mac – Saw them in concert at Wembley last night. A little treat from Karen – Absolutely fantastic!

The wiring continues, after each circuit is wired up a check to see if it’s working as expected. All good so far!

As mentioned previously I need to protect the SkyView from a surge from the Amp Shunt so I’ve purchased some 1 amp inline fuses. They are very small…

… and make for a very neat protection solution when positioned inline.
With all the wires ‘under the bonnet’ it’s difficult to make it all tidy…
…but I layout all wire first to see where best to route them before trimming to correct length and terminating. All these will need to be secured too with stand-offs as required.
The servo looms are next. I’ve installed the looms as far as the cockpit and now need to terminate each wire and make up the connector. It requires crimping the pins on each wire with a 4 way crimper.
After crimping they are inserted into the D9 block…
…and the backshell is added. Fairly straightforward but you have to make sure that the crimps are secure. There are two of these, one for roll and one for pitch. Once made up they are plugged onto the SkyView network hub.
Next up is to finish off the engine sensor connections. The correct pinout from the D37 connector is identified and the wire routed as described before trimming to the correct length and terminating. In this case a uninsulated spade connector that slips over the sensor connector. This is the LH CHT sensor…
…and the oil temperature sensor.
A quick check that everything is working. The CHTs, EGTs, Oil Temp, Fuel pressure, Oil pressure, Voltmeter, Ammeter and autopilot have now been completed and work as expected.
