RPM Module:
The RPM module receives and processes signals
from up to 2 inductive pickups for measurement
of engine RPM. Each input has an automatic
gain circuit to compensate for a wide variance of
ignition systems.
The green LED glows when the RPM module is
receiving power.
The amber LED flashes when an RPM signal is
detected. A steady flash rate, proportional to
engine RPM, indicates a good RPM signal.
These connectors are the inputs for both primary
and secondary inductive pickup clips. Either
input may be used with a primary inductive
pickup or a secondary inductive pickup on a
single ended coil. Both inputs can be used for a
wasted spark ignition.
