The centerpiece of this comprehensive electrical wiring kit is the ratcheting hexagonal crimping tool. In addition to the generous assortment of Lucas-style bullet connectors and female sleeves, is the bullet closing tool. This kit is indispensable for the restorer of vintage British motorcycles or automobiles.
The kit contains the hexagonal crimping tool, bullet connector closing pliers, (20) brass 1mm bullet connectors, (20) brass 2mm bullet connectors, (20) 1mm tinned connectors, (20) female sleeve connectors, and (10) double female sleeve connectors.
The hexagonal crimp offers an even grip on the wiring when the correct gauge of wire is used with the appropriately sized bore of the Lucas-style 4.7mm OD bullet connector. Minimum recommended wire size for crimping with this tool is 18 gauge. The bullet connectors can also be soldered, if desired, although the crimping method is considered quicker and is the practice of many service shops specializing in vintage British motorcycle repair and restoration. The bullet connector closing pliers aid in properly seating the bullet into the female sleeve connector and prevent damage to the wiring insulation caused by using needle-nose pliers to push the bullet into the sleeve.
The 1mm bullet connectors are compatible with 18 gauge stranded wires, while the 2mm bullets will accept the larger diameter 16 gauge stranded wires. It is critical the crimp is placed at the narrowed waist of the bullet connector to ensure adequate conductivity between the wire and bullet. Generally about 7-8mm of insulation is stripped from the wire, resulting in a visible tuft of copper wiring above the tip of the connector. Tinning stranded wiring is not recommended when hexagonally crimping the bullet connector.Â

Full disclosure: I’m using these tools and connectors on an MGB, not a BSA or Triumph bike. British cars are full of bullet connectors too, mostly on exterior lamps. Lucas gets a bad rap for lousy electrics, but most of it comes down to corroded, loose connectors and bad grounds. This set and a little bit of dielectric grease will go a long way in making things work better.
