Bob - 

Here is the wiring diagram that Mark is planning on using on his Pacer.  Let me know what you think of it and changes that you suggest.

When the avionics switch fails, all avionics will be lost.  I recommend not having an avionics switch.  If the builder insists on an avionics switch, then I suggest having a redundant current path.

There should have been 4 or 5 files, each one a section of the whole drawing.  I will try to send it again.

The ground, at the very left side of page 1 above the alternator, is shorting out the electrical system.

 The voltage regulator â€œenableâ€ terminal has two wires attached to it.  The shortest of the two wires is in parallel with the alternator field switch and prevents the switch from opening the circuit.

Alternators have internal diodes.  An external reverse-current diode is not usually installed.  The diode could get very warm depending on the type of diode and current through it.   Will that diode have any affect on voltage regulation?

Is 10awg wire big enough to handle full alternator output current without over heating?

The Pacer is a certificated airplane.  Seems as though it's electrical  system should conform to the original as it left the factory and/or FAA approved  modifications there to.

  

 What am I missing?

The title that says, "Bearhawk"?  There is a Bearhawk Patrol, but I am not familiar with a Bearhawk Pacer.

Marvin;  

   

Couple of comments;  

   

Don’t understand the second battery depicted as a panel common ground buss?? (Also depicted with negative terminals at both ends??)  

   

On the voltage regulator, the ground, enable, and sense terminals are all tied together and also to both ground and battery power. This will either blow fuses, trip breakers or release valuable smoke from the wires. Also as shown, if the ground is corrected, the alternator field switch has no control as there is an alternate path in parallel from the first fuse on the main buss. (labeled main?? Hard to read?) This part of the circuit will simply not work as shown.  

   

Wire sizes seem a little strange. Some are marginally small others excessively large. How were these chosen??  

   

The main battery symbol is shown with two positive terminals. The right hand, grounded terminal should be negative. (short line as opposed to long)  (semantics, I know, but- - )  

   

A single switch removing all avionics power is generally considered a bad idea as it is a single point of failure. (although used on many production aircraft for years.) (your choice, it will work, but - - )  

   

The reverse current diode really serves no purpose as the rectifier diodes in the alternator are in series with it anyway.

  Not a thing. I'm not sure that Marvin intended

  to post this to the List . . . he has a friend

  in AK who is rebuilding a Pacer and I'm pretty

  sure this is his first whack at a wiring diagram.



  I'm copying pages from another wirebook to assemble

  a page-per-system approach that will produce

  more readable copy and give us a better foundation

  to sift the details.



  It's not a bad thing that the List be involved,

  I'm pleased to see the degree of interest and

  participation. I'll publish the wirebook to the

  List as well - 



  I think "Bearhawk" may be Mr. Mark Moyle's 

  handle . . .



  Thanks for participating guys . . . watch this space . . .

   Has he actually purchased the Plane Power hardware yet?

   The regulator in his drawing is a universal replacement

   for a host of applications, some of which date back to

   years that alternators were fitted with auxiliary sense

   terminals for controlling a field relay.



   His diagram for the alternator appears to be a clone

   of the installation instruction drawings for the R1224

   regulator which assumes ALL of the legacy features

   are present. If he has purchased this hardware,

   we need to know which alternator is in hand.

Why in the world would you file a 337 if there were no changes other 

than the schematic drawings? 337 is for changes to the aircraft that fit 

the FAR43 Appendix A definition of a Major alteration or repair.

If there are actual changes to the wiring, then the A&P approving will 

have to make the determination whether the changes are "major" or not. 

If the changes are very likely to be "major" then the FSDO needs to be 

contacted and field approval obtained *before* anything is actually 

changed. Otherwise the owner might not be happy to have a changed 

aircraft that the FAA will not approve.

Yes, the hardware is all at hand.  I talked to Mark last night and he is supposed to be joining this list.  This is going to be a good learning experience for me, except for the usual back and forth as to change from original wiring or not.  THAT decision has already been made, as you and I discussed, with the goals of installing more a more modern wiring design using updated components , keeping everything as simple and light as possible.  I have not discussed the procedure favored by my supervising mechanic yet as to how to get the changes approved, but if it has been approved before, I have copies of the old approval, and follows approved wiring practices, with proper wire size, good workmanship and good components, he said he has no problem with the paperwork.  Once we have a design, I will give it to him for his approval, and go / no go decision.  



I will forward your email on to him, and get him signed up to the list.

That post was copied from the Bearhawk list.  The airplane is / was an original Pacer that I sold to Mark a couple of years ago.  It was wrecked due to the landing gear folding up from a weld repair turning loose, likely due to the extreme cold.  Mark is rebuilding it with extensive modifications.  There is an extensive thread of the rebuild, step by step on the Short Wing site.  Additionally, I am starting a PA22-20 project that I picked up covered and painted in Waverly, IA a few years ago, and will be doing a similar panel.  The diagram is from a Super Cub builder that used that wiring design for the rebuild of his Super Cub, with the wiring approved by his mechanic and is now flying on the airplane.  So we know it has been approved and installed at least once.

Donâ€™t know the answers to your questions but I hope Mark will get signed up on the list today to provide the answers.  But I appreciate the input and I am saving your comments to make sure these issues are resolved as I hope the design will be used in my project once this group gets done â€œtweakingâ€ it!

This is a certified airplane.  Prefer to start with a design and drawing that we know has been approved and is flying on a 337 in a similar Piper Product so we have a â€œhistoryâ€ to cite.

This will either blow fuses, trip breakers or release valuable smoke from the wires. Also as shown, if the ground is corrected, the alternator field switch has no control as there is an alternate path in parallel from the first fuse on the main buss. (labeled main?? Hard to read?) This part of the circuit will simply not work as shown.

 

Wire sizes seem a little strange. Some are marginally small others excessively large. How were these chosen??

 

The main battery symbol is shown with two positive terminals. The right hand, grounded terminal should be negative. (short line as opposed to long)  (semantics, I know, but- - )

 

A single switch removing all avionics power is generally considered a bad idea as it is a single point of failure. (although used on many production aircraft for years.) (your choice, it will work, but - - )

 

The reverse current diode really serves no purpose as the rectifier diodes in the alternator are in series with it anyway.

Okay, I have attached the four files.  We will see if they come through.

Bob is correct.  But it is fine that it is on the list, as  I thought everyone could learn from my ignorance.  The post was originally from the Bearhawk Builders List and forwarded to Bob.  Yes, this is Mark and my own first crack at a wiring diagram, and since I have 3, maybe 4 airplanes to wire in the next several months, I need to learn and develop a good generic wiring design that can be easily approved on a certified airplane without a lot of drama and effort.  Those of you that have owned and flown Pacer will appreciate why the wiring needs improvement.  I completely rewired my Pacer when I got it 20 years ago, but used all the old components and just replaced what was there.  The project I am doing now will be for sale when it is finished, so I want something that is simple and trouble free, and wonâ€™t be coming back for me to repair.  It also needs to be similar to other GA airplanes so that any mechanic will now how to repair it (I will have a complete wiring diagram in the paperwork).  I love that Bob is already on that track with the page per system approach.  That is already a benefit for my understanding and records.

  Not a thing. I'm not sure that Marvin intended  to post this to the List . . . he has a friend  in AK who is rebuilding a Pacer and I'm pretty  sure this is his first whack at a wiring diagram.  I'm copying pages from another wirebook to assemble  a page-per-system approach that will produce  more readable copy and give us a better foundation  to sift the details.  It's not a bad thing that the List be involved,  I'm pleased to see the degree of interest and  participation. I'll publish the wirebook to the  List as well -   I think "Bearhawk" may be Mr. Mark Moyle's   handle . . .  Thanks for participating guys . . . watch this space . . .
