Mar 26, 2022     Engine wiring - (3.1 hours)       Category: Firewall Forward

Worked on the firewall-forward wiring:

1. Spliced the Main Alternator and Stby Alternator field leads. Heat-shrinked and bundled them into two bundles that will be attached to the engine mount with Adel clamps.
2. Removed the top skin to give better access to the back of the firewall so I could add another Adel clamp.
3. Deburred all the new holes in the fuselage and cleaned off the blue index marks used to drill the holes.
4. Added the clamp at the top left part of the firewall to hold the fire-sleeved wires running to the engine sensors.
5. Added another pair of clamps on the engine mount to hold the end of the firesleeve.
6. Twisted and heat-shrinked the wires coming out of the Oil Pressure and Fuel Pressure sensors. [No photo]
7. Attached a 90-degree AN fitting to the main fuel line, then attached the fuel line at both ends.
