| -4- (1) O.C. volts 15.2 to 16.2 volts. (2) Output at 13.0 volts. 11.0 to 14.0 amperes. (3) Output at 15.0 volts 2.0 to 8.0 amperes. Note. The standard chassis ammeter specified above, is for the purpose of measuring the effect of regulator operation, on the ammeter indications. The regulator causes the ammeter needle to oscillate more or less. The chassis instrument should be kept under observation and the amplitude of the swing of the neexdle estimated, as far as possible, at the various, speeds. The needle at no time should swing over more than two divisions. Hs{Lord Ernest Hives - Chair}/Wst. | ||
