There seems to be a general feeling here against the use of the single distributing fuse, which, if it goes, puts out all the lights and puts out of operation the Klaxon, Ignition and Starter Motor actuation, and possibly more important than all, the supply to the inspection lamp plug socket. It appears to us that either no fuse, or more than one fuse, should be used on the distribution circuit.
