| -2- Contd. (d) Fuse in control circuit. (e) Fuse in negative circuit (f) Fuses in both circuits. Initially, fuses of 15 ampere capacity should be tried, later on, when we obtain them, fuses of 20 ampere capacity should be tried if necessary. Each case should be investigated with the dynamo in both a hot and cold condition. For passing the short circuited current an independent switch should be joined as a shunt across the cutout to simulate the condition of the cutout sticking in the "on" position.
