I recently bought myself a bootlace ferrule crimper, and a set of various size ferrules, to produce more reliable wiring terminations.
Tonight I put it to the test with very good effect. I re-terminated my fuel boost pump, flap position sensor, and flap motor wires.
This took me much longer than it should because I accidentally stripped one of the tiny screws in the flap position sensor terminal block. I had to install a new one.
