| -5- The location of the regulator on its base, and that of the base on the dashboard of the chassis, must be such that when in its final position, the regulator is not more than 15° from the horizontal. Complete Unit. All connections should be checked to see that they are sound, especially those between the regulator and the resistance wire. This last precaution is to make sure that the regulator cannot be in operation without its resistance unit. The complete unit, with cover on shall then be mounted in a position similar to what it will occupy on the chassis, and connected to a shunt dynamo and a suitable 12 volt battery. A variable (carbon) resistance followed by a standard chassis ammeter should be inserted in the main circuit between the regulator A terminal and the battery. A voltmeter should be connected so as to measure the dynamo terminal volts. The following tests should now be carried out :- (1) Open Circuit Volts. With the regulator cold the dynamo shall be gradually speeded up and the O.C. terminal volts observed until the regulator commences to operate. This will be indicated probably by a fall in the terminal voltage and a flickering of the instrument needle. The speed of the dynamo | ||
