In the illustration the alternator panels are shown at the left and the feeder panels at the right.
For the alternator panels, instruments of the vertical edgewise type are used.
Each vertical row comprises the measuring instruments for an alternator.
In some cases an alternator is used in place of the battery B, Fig. 4, and when this is done the break M can be dispensed with.
When the ends of the coil are connected to the terminals of an alternator the disc is set in rotation.
Even when making such observations with an alternator one is apt to be mistaken.
