Optional Digital Tachometer (not included)
A n o p t i o n a l d i g i t a l
tachometer is available that
can be directly connected to
the ignition and display the
RPMs of the engine. This unit
can be installed on the
aircraft or used to spot check
the Engine RPMs. Do not install or uninstall the Digital Tachometer
while the engine is running.
Many of the DLE Ignition
modules have an additional
lead to plug into the optional
tachometer. If your ignition
module does not have this
additional lead, the digital
tachometer can still be used.
Simply use the Y-harness
(included with the Digital Tachometer) to connect to the pick-up lead
from the engine. Be sure to secure all connections and to secure
the Digital Tachometer or leads on the aircraft used.
