Vans Aircraft RV-12 Airplane Build, Section 45A: Firewall Forward Wiring Harness (part 2)

Reference for this entry: pages 45A-02, 45A-03; 1.5 hours

I had a hard time finding some of the part for today's work on the RV-12 airplane, namely the rectifier regulator and starter relay. These are in a box that are shipped in the engine crate. I'm not used to engines coming with the accessories. In fact, the Rotax even comes with oil!

Step 4: Secure the Odyssey Battery. Builder's note: The was done later after the paint on the hold down dried.

Step 5: Install the Master Relay, Starter Relay, Manifold Pressure Sensor and Rectifier Regulator to the Firewall.

Builder's note: On the Manifold Pressure Sensor I had to use thin washers so as to have enough threads showing for the nutplates.

Reference: page 45A-03

NOTE: DO NOT CONNECT the Battery Ground Cble to the battery at this time!

Step1: Install an insulated boot onve the end of the WH-P150 Battery Power Cable with the smaller ring terminal. Attach the Cable to the positive side of the battery in the RV-12.

Step 2: Using the hardware called out by Van's Aircraft attach the Battery ground cable to the Oil Reservoir Brace with the Engine Ground Cable.

Step 3: Install a Insulated Boot over the unconnected end of the Battry Power Cable and tape ti in place to isolate it from possibly touching the airframe.

This completes page 45A-03 and today's work on the RV-12 airplane.
