Secure theadjustment by tightening the twoscrews.(g)Push down on the voltage regulatorarmature until the voltage regulatorcontact point barely touches theadjusting screw. Measure theairgap between the coil core and thearmature of the voltage regulator.Do not measure between the coreresidual brass pin and the armature.The correct voltage regulator airgapis 0.084 inch.(h)Adjust the correct regulator airgapto 0.115 inch in the same manneras for the voltage regulator unitdescribed in g above.(2)Electrical adjustments. Install set of testadapters as illustrated on figure 9.Note.Refer to C figure 9 and polarize thegenerator.(a)Cutout relay closing voltage. Withvoltmeter connected as shown in D,figure 9 start the engine and slowlyincrease speed until the cutout relaycontact points close. Observevoltage reading at which thisoccurs. It should be 25 to 27 volts.If adjustment is necessary turncutout relayadjusting screwclockwise to increase orcounterclockwise to decrease theclosing voltage. Set closing voltageat 26 volts.34
