March 8, 2008 - AN Shunt, Firewall Recess, Fuel Tube

I trial-fit the engine mount and discovered that the Current Limiter was interfering with it.  So I had to move the Current Limiter an inch to the left.  Glad I caught it now. 
  
The next item was the AN Shunt, mounted vertically on the left.  The purpose of the AN Shut is to measure the current and send it to the Anmeter which for me will be the Dynon.  I spent a lot of time researching where in the electrical system and where on the firewall the AN Shunt should go.  I thought about putting it to the right of the gasolator, above the current limiter.  But I ended up putting it to the left of the battery box because I figured it would be easier to wire up there.  Plus I didn't want it right next to the gasolator.  My AN Shunt will display the alternator output.  The flow goes as follows:  Alternator --> Current Limiter --> AN Shunt --> Starter Contactor --> Master Relay -->  Battery/Main Bus. 
  
 I installed right angle nutplates in two spots (see vertical arrows).  Then I riveted the brake pedal bar bracket to the firewall (see horizontal arrow). 
  
I mixed up some Rage Gold filler and spread it on the empennage fairing where I had done the epoxy work.
  
The idea is when the fairing is painted and done, you won't know that I had grafted on a new piece.
  

I fashioned the 3/8" aluminum tube which runs from the aux fuel pump to the gasolator.  This was probably the easiest tube I've had to make.  Just a single bend.  The flaring tool made the flares easy.
