Optional Digital Tachometer
An optional Digital Tachometer
(DLEG5525) is available that
can be directly connected to
the ignition and display the
RPMs of the engine. This unit
can be permamently 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.
