| -4. distortion of this part may upset the adjustment of the contacts, and consequently the operation of the regulator. 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 cutout connection to terminal A should then be removed, and the unit, with cover on, 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 switch, variable (carbon) resistance, and a standard chassis ammeter should be inserted in the main circuit between the regulator, A terminal and the battery. A voltmeter should be connected to regulator terminals + and E so as to measure the regulator terminal volts. The following tests should now be carried out :- | ||
