The Dyna S ignition from Dynatek fits all Harley-Davidson cam covers on Big Twins (1970–1999) and Sportsters (1971–2003). It can serve as an electronic replacement for the original breaker points and condenser through 1978 or as a substitute for faulty control modules on Late Shovel and Evolution engines. Models originally equipped with electronic ignition require an additional advance mechanism.
The Dyna S switches much more precisely than mechanical points. The advance timing adjustment is purely mechanical and, once correctly set, requires no maintenance.
Available as Dual Fire (both cylinders fire simultaneously, as in the original) or Single Fire (each cylinder fires separately at the end of its compression stroke).
Street use with 5 Ohm coils only! 3 Ohm coils for race only! Do not use with WW 12-225!
Tach-Adaptor must be used whenever a Dyna S Single Fire ignition system is installed on a H-D with electronic tachometer. WW# 12-518 works with most tachs on the market. Some exceptions require WW 12-519 (T103). In this case we refund the non-compatible adaptor.
For applications with one spark plug per cylinder head, two ignition coils with one high-voltage output each must be selected.
For applications with two spark plugs per cylinder head, two ignition coils with two high-voltage outputs each must be selected, i.e. in basically standard "dual fire" ignition coils.
