| Contd. -13- EFC {E. Fowler Clarke - Electrical Engineer} 2/T11.12.17. of Remy 6 condenser were tried by connecting condensers in series with this. The smallest of these produced nearly the maximum effect on the secondary spark. It was proved that by the time the normal working capacity was reached, the secondary voltage had passed its maximum and begun to decrease. On the other hand although the primary sparking was improved at the most rapid rate at first, it was still undergoing some little improvement at this time. Experimental for Remy 6. There is rather more sparking at the contact points of Remy 6 than at those of Remy 12, this being due asw we have amply proved, to the position of the condenser in the coil. Upon removing the condenser connection and connecting Remy 12 condenser across the points, this is reduced, at any rate, of the two components, there now remains no evidence of the "arcy" component of the spark of which some evidence had previously existed. When the Remy 12 condenser was connected in addition to that of Remy 6, missing started on the 6 mm. secondary gaps. Primary spark as in preceding paragraph. Upon connecting Remy 12 condenser in addition to Remy 6 through several feet of wire, the effect on the secondary was the same but the primary spark was not reduced as much. Contd. | ||
