+ | Typical options for Sportster Ignition Configurations (up to 2003): | ||
+ | |||
+ | 1) Older OEM Ironhead Models | ||
+ | - Points to create spark | ||
+ | - Mechanical Advance to create an advance curve | ||
+ | - Coil is 5.0 ohms to match use with points | ||
+ | |||
+ | 2) Stock EVO Configuration (Later model Ironheads & EVO up to 2003) | ||
+ | - Cam Sensor Plate (electronic trigger) - in place of points | ||
+ | - Ignition Control Module - rearward from battery (or other places) | ||
+ | - ICM has electronic curves for advance | ||
+ | - This module uses a VOES to switch between 2 curves - Vacuum Switch | ||
+ | - Coil should be 3.0 ohms | ||
+ | |||
+ | 3) Some Only Eliminat Points (older Ironheads) | ||
+ | - Electronic Trigger - Dyna S - DS6-1 model | ||
+ | - Mechanical Advance is still used for advance curve | ||
+ | - Coil can be OEM 5.0 ohm | ||
+ | |||
+ | 4) Eliminate Points & Mech Advance (and/or stock external ICM) | ||
+ | - Electronic Ignition Module - Ultima 53-644 - In nosecone | ||
+ | - This module includes electronic curves for spark advance | ||
+ | - This module uses a VOES to switch curves - Vacuum Switch | ||
+ | - Coil is 3.0 ohms | ||
+ | |||
+ | The 2004-later models all implemented the Crank Position Sensor which eliminated the Cam Sensor Plate. | ||
