The distributor was standard except for the sparking points which were of Nichrome. Running speed 500 rpm. Steady sparking was obtained for 15 secs before taking each reading. Remy coils were used for the leakage, as in the test on (Contd) Signed This Sheet must be filed on completion of the work. | ||
