- 1). Remove the aircraft's canopy by disconnecting the mounting clips, then slide the canopy off the fuselage. Find the faulty wire, often identified by melted insulation or cracked solder joints.
- 2). Heat up the solder iron, then touch the hot tip to either end of the faulty wire. Pull the wire from the fuselage, then use it as a template to cut a second wire of equal length. Remove 1/4 inch of insulation off both ends of the wire with the wire strippers.
- 3). Touch a small amount of solder to the hot iron, then wipe the two ends of the wire with some solder (this is a process called tinning). Press one end of the wire against the connection point in the fuselage, then hold the solder iron against the junction to heat it up. Apply solder to the heated joint to fuse the connection. Repeat this for both sides of the wire.
- 4). Close the fuselage by clipping the canopy back into position.
