Optional Digital Tachometer
(not included)
An optional Digital Tachometer
(DLEG5525) is available that can
be directly connected to the
ignition and display the RPM
of the engine. This unit can be
installed on the aircraft or used
to spot check the Engine RPM
. Do not install or uninstall the
Digital Tachometer while the
engine is running.The Futaba
®
DSC Charge Adapter (FUTM4243) can be mounted in the fuselage
and allows easy external plug-in of the Digital Tachometer.
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.
