Coming MAY 2020

Beechcraft wiring diagram manuals do not list wire lengths like most Cessna WDM's.  It's best to remove your wiring and send to me for replication.  This way we are sure you receive the correct length, wire and lug size.  You may also provide your own measurements.

Engine Grounds

image7

Early 150 and 172 Cessna's terminated the battery ground braid at the nearest engine mount isolator bolt.  By the late 60's the battery ground was moved below the battery to a firewall bracket.  Item 10A is the photo to the left shows ground strap 0412007-8 installed between the engine and engine mount.  Relocating the battery ground and bypassing the engine mount isolator provided a much better ground path for the starter and alternator.  Owners of older models should seriously consider updating to the later model dedicated battery and engine grounds. 


PPH engine ground is American made AA59569R30T0562 tin plated 7/8" wide 4 AWG copper braid with tin plated ferrules or M20659 Burndy YAV lugs with 3/16” hole and 5/16” hole.  Lentgh is approximately 7" center to center.


$25

Beechcraft, Piper and other models available by request.

See my TIPS page for grounding information.  I can build whatever your aircraft load requires.  Braids can be doubled for 6 cylinder high electrical load requirements.

Antenna Coax Cables

Certified RG 400 coax is available with Amphenol BNC connectors for nav/com and TNC for GPS antennas.  AMP connector substitution by request.  Labels included.


I can solder various coax tray connectors to minimize splices.


RG 400 - $1.75/ft


Straight Plugs(male) BNC and TNC - $12 ea installed.

90 degree BNC - $35 each installed


90 degree TNC - $15 each installed

Avionics Harnesses

image10

Stack harnesses are hand tied with each wire group such as audio, lighting, powers and grounds combed out separately to ease installation.  There are cheaper ways to do it, but none more sanitary and organized.  Avionics harness quotes include only wiring and my labor. 

I do not build legacy Collins, King or Narco harnesses except KX155.

Connector kits and components of incomplete connector kits will cost extra.

Avoid buying used avionics without the tray and all connector assemblies.

 Buyer Beware: Garmin does not sell their threaded backshell retainer separately.  This is due to customers buying installation kits for competitor slide in replacements of Garmin units.  ITT Cannon M85049/48 style backshells were designed to be attached from the outside.  Garmin's threaded backshell retainer is proprietary and manufactured for Garmin connector screws to attach from inside the trays.  If you buy used Garmin avionics, make sure the seller sends all associated connectors and mounting hardware.  

Stack harness with audio panel, dual navigators and transponder - $1500

This approximate estimate of a typical stack includes my labor and wiring only for 4-6 place audio jacks with music soldered, dual NAV indicator break outs and encoder break out.


Add $150 to mount your encoder to your transponder tray.  See gallery below.

Connector kits and contacts sourced by me will cost extra.
