| X2515 PN.{Mr Northey}5/WTL.2.30. S/W EFC...from PN.{Mr Northey} [Text struck through] FUSES - "PHANTOM II". Fuse No. 6 is in series with three other fuses which are in parallel, the latter carrying the interior lighting, Klaxon, cigar-lighter etc. It would be useful if it could be made clear to owners' drivers as to what strength of fuse is desirable in No. 6. Because if a man sounds his Klaxon and lights his cigar at the same time as his interior lighting is on, No. 6 fuse may burn out quite unnecessarily, unless it is made sufficiently heavy to stand up to the greater current. Do you agree that this fuse had better always have two strands of the fuse-wire supplied whilst the others have only one. We meet cases whether this No. 6 fuse is really breaking circuit.
