| Contd. -3- The average current taken by the primaries of the coils at 12 volts when hot was as follows :- TR. {Capt. F. W. Turner - Finance} 1 1.15 amperes. TS.6. 1.115 " TR. {Capt. F. W. Turner - Finance} 5 1.15 " 4353 1.26 " It will be seen that the redmanol encased coils in th both cases gave better results than the stabalite at all four temperatures 77°, 82°, 87° and 100°C, and it is suggested that they should be given further thrashing tests on a chassis in a thoroughly hot condition.
