[[techtalk:ih:engctl01d|See more on the Magnavox Ignition System]] \\ | + | **(1980 to 2003)** Components include a timing rotor (timing cup), sensor plate or inductive pickup, ignition control module, ignition coil and spark plugs. For electronic advance, the inductive pickup generates TDC pulses that are sent to the solid state Ignition Control Module (ICM). The ICM computes ignition timing advance and coil dwell. In 1983, a Vacuum-Operated Electric Switch (VOES) was added to switch between 2 different spark advance curves built into the ICM. ((1959-1985 Clymer Sportster Repair Manual pg 229)) |
