To Order No Customer's No. 4 19 would be instructive to have a series of condensers made up, ranging from about .25 to .30 mf in steps of .01mf and tested on a standard distributor for spark length. From this a definite upper limit could be decided upon. With these condensers available the opportunity has been taken of using one of the largest to check the calculated resonance obtainable with the Remy ignition coil 284.B. This while showing what was wanted, broke down (Cont'd) Signed This Sheet must be filed on completion of the work. | ||
