Electrical Wiring Reference: Drawing 9451061, Diagrams 1 to 14 Photo Parts Required: As Detailed Materials Required: As Detailed Procedure: All wires should be colour coded in the following way: Wires banded with or Yellow are from the (+12V) Positive bus to positive marked positions on the components of the aircraft. Wires banded Black or Green are from the (Earth) Negative bus to negative marked positions on the components of Aircraft systems. Wires banded White are from Sensors or Pick-ups to Sensor positions on components of the Aircraft systems. Ensure that all electrical wiring is routed away from hot and moving components and that it is secured to the engine mount in the engine compartment. Where the cable loom passes through the firewall it must be secured in punched grommets, holding the wire in the centre of the grommet. In the cabin area, the loom passes through the centre beam which provides protection. Ensure that wires are restrained by zip-ties before entering and after leaving the centre beam. Ensure they do not contact moving parts. Tachometer and Hourmeter Wiring (refer to Drawing 4119234, Diagram 1) Tachometer Negative (3) to Earth Bus #1 Tachometer Positive (4) to Instrument Bus #1 Tachometer (8) through Left grommet to Wire tachometer pick-up Tachometer (7) through Left grommet to Black wire tachometer pick-up Oil Pressure Wiring (refer to Drawing 4119234, Diagram 2) Black Oil Pressure Gauge Negative (-) to Earth Bus #2 Oil Pressure Gauge Positive (+) to Instrument Bus #2 Oil Pressure Gauge Sensor (S) to Oil Pressure Sensor (Fwd Top Eng) (G). Oil Temperature Wiring (refer to Drawing 4119234, Diagram 3) Oil Temperature Gauge Negative (-) to Earth Bus #2 Oil Temperature Gauge Positive (+) to Instrument Bus #2 Oil Temperature Gauge Sensor (S) to Oil Temperature Sensor (Lower Left Eng Sump).

Cylinder Head Temperature Wiring Instrument, Loom and sensor is supplied by manufacturer. These must be installed as per directions. Thermocouple wire is located under the rear spark plug of number 4 cylinder. Note:- The ring terminal should be carefully removed and replaced with a 12mm ring terminal. Ensure that wire is not chaffing on the fibreglass air duct or cooling fins Engine Hourmeter Wiring (Optional) (refer to Drawing 4119234, Diagram 4) Hourmeter Positive (+) to Instrument Bus #1 Black Oil Pressure Switch to Engine Sump Bolt. Black Hourmeter (-) to Oil Pressure Switch (Fwd Eng Left) Air Time Hourmeter Wiring (Optional) Hourmeter Positive (+) to Instrument Bus #1 Black Hourmeter (-) to Airswitch Black Airswitch to Earth Bus #11 Note:- Locate airswitch inside the instrument panel and to the left. Adjust the airswitch to 35-40 knots. Earth Wiring Black Battery Earth Negative (-) to Firewall Earth (Engine Bay) 10 Gauge Black Battery Earth Negative to Earth Bus #6 10 Gauge Strobe Power Supply Wiring (refer to Drawing 4119234, Diagram 5) Main Bus (3) to Strobe Fuse. Strobe Fuse to Strobe Switch (Lower) Strobe Switch (Upper) to Strobe Power Supply (+) Black Strobe Power Supply (-) to Earth Bus #5 Strobe Power Supply is fitted to the right hand side of the fuselage forward of the Sound Curtain Support. The fuse holder should be located on the left side of the lower instrument panel. Strobe Light Wiring The loom is partially assembled for fitment through the roof mount and out of the spine channel beside the VHF Antenna, dropping down to the Power Supply.
