Solenoids: Master Relay and Starter Relay
Most aircaft are going to have a master relay and a starter relay. Dick Koehler discusses operation and installation of the relays. Dick is a technical counselor for EAA Chapter 186, an A&P mechanic with IA, and a SportAir Workshop instructor.
Antenna Ground Plane
Antenna ground planes for composite or wood aircraft can be made in various ways. EAA Technical Counselor and A&P/IA mechanic Dick Koehler demonstrates how to use copper foil tape to make a light weight and effective antenna ground plane.
Electrical Volt-Ohm Multimeter
Dick Koehler discusses the use of a digital volt/ohm multimeter which is a useful tool for diagnosing electrical issues.
Voltage Regulator Overview
EAA Technical Counselor and A&P/IA mechanic Dick Koehler shows the inside of a mechanical voltage regulator and discusses the component parts and how it all works to regulate voltage in an aircraft's electrical system.
Molex Avionics Connectors
Dick Koehler demonstrates how to make a Molex connector commonly used in avionics installations. Dick is a Technical Counselor for EAA Chapter 186, A&P aircraft mechanic with Inspection Authorization (IA), and SportAir Workshop instructor.
Labeling Electrical Wires
Labeling electrical wires is sometimes overlooked during the building process. EAA volunteer Fred Stadler shows how effective a label maker can be to mark heat shrink tubing and install on wires as a method to mark wires for later identification.
Key Switch Installation
Tracy Buttles from the EAA staff demonstrates how to install a ignition key switch into an instrument panel in a way that locks it in place and prevents it from rotating within the mounting hole.
