| contd :- -3- engine cyl. blocks. On the inside of the Vee the engine end fixing is easy, but on the outside for the exhaust plugs, there is no convenient stud. The only way being to lead the wires to the brackets holding the H.T. leads which has a stud fixed in the cyl. blocks. Chater-Lea Terminals. Similar remarks apply to the Chater-Lea terminals on the H.T. wires. These terminals are too long (fig.1), they are liable to short on studs etc. especially if a short bodied plug is used. We suggest that if it is absolutely necessary to use this type of terminal that they should be made much shorter as in fig.11 and the wire could be fixed each side of the terminal hole. On several of the wires it is possible to turn the Chater-Lea terminals round so that if turned sufficiently long enough the wire would break. They really require two pointed tabs so that when the wire is fixed and soldered the tabs could be bent into the insulation and therefore prevent this turning - fig.111.
