Instruction manual

Screwed wire connector

A LUCAS screwed connector of the type shown in Illustration 37 is used in the wire

connecting the positive terminal of the battery to the input side of the ammeter (the

wire has yellow and black coloured sleeves) in the head lamp. It is made up of four

parts. One part, a metal sleeve, is threaded internally and accommodates a collet

which is placed on the end of one of the wires to be connected in such a manner that the

wire ends protrude through the centre of the collet. The third metal part screws

Into the first and has passing through it the second of the wires to be connected.

The wire ends are splayed out and the act of screwing the two threaded parts together

binds the ends of the two wires, thereby making a good electrical contact that can be

immediately broken as, and when, it is wished to remove the battery from the machine.

A rubber sleeve encircles the whole assembly, serving the dual purpose of insulation and

prevention of loss through vibration.

Terminals

The earth wires (two—one from regulator, the other from negative terminal of battery)

and the high-tension wires (two—one on sparking plug end of each wire from magneto

to sparking plug) have terminals of the solid sleeve type having an eye at the extreme end.

To make such a connection, it is necessary to bare the end of the wire for a ", pass the

terminal over the wire so that the bared end fully enters the reduced core of the terminal

and then flatten that part by either pinching in a vice or by hammering.

The two earth wires, mentioned above, are connected to the " earth " by securing them

to the left side of the seat lug bolt (which is situated just under the saddle) by means of a

washer and a screw. It is essentia! that the connections are kept clean and the screw

must be kept fully tight.
