Daytona's Twin Tec model 1005 Internal Ignition unit is intended for those who want a flush-mount ignition system. For this cleaner look, the model 1005 ignition replaces all the Harley-Davidson OEM ignition components, including the bulky wiring harness and external module. This ignition unit is triggered from the stock timing rotor at the end of the camshaft and mounts inside the engine nose cone. It is intended for electric start applications only. Four rotary switches are used to set the operating modes (such as single or dual fire, advance curve family and multi-spark), adjust the timing advance, and select the RPM limit. Two diagnostic LEDs indicate general status and the status of the vacuum switch (VOES). The status LED is also used for static timing, as it will flash when the engine reaches top dead center (TDC).
