| Though the ESL2 series Safety-Shielded Secondary
leads suppress RFI (Radio Frequency Interference) with the lowest
level of energy losses, the fine wire, helically-wound conductor
of the R757 ignition cable requires that its terminations be
of a style where the ignition cable does not have to be pulled
out of or off of the ignition system components to which it is
connected. For RFI elimination when a coil is being used that does not furnish a threaded termination, we find that the R757 ignition cable is too fragile to do the job over the long term. For those applications using such "unshielded" ignition coils (eg., Altronic 501061, 291001, 591010 ; Fairbanks-Morse PPT2477P, PPT2477L), we recommend that our RSL2 series of secondary leads be used. These leads utilize a ceramic, wire-wound resistor with a nominal impedance of 5,000 Ohms. It is designed for high-temperature, high voltage applications. It is fitted into the Bendos-1C ceramic that connects to the spark plug. The use of this resistor allows for the usage of Stitt's standard #757 copper conductor ignition cable. But it furnishes full suppression of spark gap arc-generated RFI. Of special interest should be the length of this resistor. Its length exceeds by a large margin the flash-over capabilities of other resistors commonly used to attenuate RFI. |
