The majority of modern ignition modules are the Constant Charge type with inbuilt current
control. Current control limits the primary current to avoid damage to ignition components,
primarily the Ignition Coil. The primary current charge time is read in milliseconds and is
controlled by the coil charge time field. The primary charge time will usually vary between
1.4 ms and >4 ms (some older systems may be up to 8.7ms) depending on the vehicle
manufacturer and ignition system used.
Coil Charge time
The following is a guide to primary charge time and spark duration time for different
coil charge times.
Coil Type Typical Charge time
Single Standard Coil 2.5 ms
Single Fast Charge Coil 2 ms
