A. This will have to be learned by practice and constant instruction at the loading-room.
Note.—The transformer, fuse, can, etc., on the compound plug are still in a state of experimentation and no method for the assembling of the latest design has been adopted as yet.
Q. How do you test the transformer?
A. With a circuit detector or galvanometer and a dry cell, as shown in figure.
Note.—In case of a break in the coil, Fig. 102, there would be no current flowing in galvanometer and no deflection of the needle would be indicated.
