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.
EAA technical counselor and A&P/IA Dick Koehler demonstrates the use of heat shrinkable solder sleeves and how they can conveniently be used to tie ground wires together.
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.
Crimping Butt Connectors
EAA technical counselor and A&P/IA Dick Koehler discusses how to use butt connectors and demonstrates wire splicing using a butt connector.
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.
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.
Electrical Volt-Ohm Multimeter
Dick Koehler discusses the use of a digital volt/ohm multimeter which is a useful tool for diagnosing electrical issues.
