Lumenition Engine Rev Limiter

The Lumenition engine rev. limiter (ERL) is designed to be used with inductive contact breaker and electronic ignition systems with fixed or variable dwell, with or
without ballast resistors and with standard or high energy ignition coils.
The rev. limiter functions by monitoring the voltage pulses at the coil negative terminal. When the engine speed reaches the set limit, the amplitude of the coil drive
voltage is clipped and prevents sufficient secondary voltage being generated in the coil, thus inhibiting the firing of the spark plugs. As the engine speed drops the voltage
limit is removed and normal coil function resumes.
The patented design ensures that no mistimed sparks are possible.
