For breaker points, the 5 ohm coils should be used or the 3 ohm coils can be used and a 1 to 2 ohm ballest resistor placed in the 12 volt line going to the coils. Generally, a ballast resistor should not be used with DYNA COILS on electronic ignitions. The secondary towers are designed to accept 7 or 8 mm automotive spark plug wire.. Turn on the ignition and measure the voltage between ground and coil [+]. A reading of about 1 volt less than battery voltage is normal due to resistance in the wiring. If the voltage is much lower, check for voltage drops across any switches, splices, connectors, circuit breakers, etc., that feed power to the coils.
Below you will find the available install guides available. If you need help please contact our Dynatek Customer Support team. You might need Adobe Acrobat® to read.. The DYNA S Electronic Ignition System replaces your entire points plate assembly and mounts in the original position. It is designed to operate with stock coils, however, it may be used with other coils that have at least THREE OHMS primary resistance.
