of the engine and contacting the plug on the outside of the crank
case. Have an assistant turn the engine over while checking this
and be sure to have the spark plug fi rmly plugged into the ignition
wire. Warning: The high voltage from the ignitions can cause bodily
harm, especially when checking for spark in this manner.
Optional Digital Tachometer (not included)
An optional digital tachom-
eter is available that can be
directly connected to the ig-
nition 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
