Fuel gauge wiring from the wing tank fuel gauges
Before completing the upholstery around the windscreen the 2 wires from the wing tank fuel
gauges must be routed down the windscreen pillars.
Drill a 5mm (arrowed above) hole slightly in
front of the forward wing mounting lug on
each side and feed 2 wires out of the hole and
back towards the rear wing mounting lug as
shown above and tape them to the fuselage.
Run the inside portion of the wires down the
windscreen pillar, holding them in place with short lengths of cloth tape as shown above right.
The wires from both sides need to meet slightly to the right of centre as shown above left.
Leave the wires hanging down about 300mm and make sure that the wires from each side are
clearly labeled [Left] and [Right] – use masking tape to label them. There is no polarity
requirement for these wires. These wires will be fitted to Connector
E
.
Note that these wires are quite separate from the wing tank earth wires that were fitted earlier.
The upholstery strips can now be glued into place to cover the wires – refer to the
Post-
Paint>Fuselage>Upholstery 1
task for detail. In the factory we place these wires before the
upholstery is fitted, which is shown in the photos above, however you could equally install all
of the upholstery apart from the windscreen strips and then fit them once the wires have been
placed.
The top ends of these wires will be connected to the wing tank fuel gauges when the wings
have been fitted to the fuselage. Leave them taped to the fuselage until then.
