Functional Check of Ignition Retarder Module
System Description:
See section 3.7.11
In addition to the periodical check (see sect. 5.3.13) the Ignition Retarder Module must undergo a functional
check after a failure during engine start.
To perform the following check, remove instrument panel cover. The module is mounted on the electronics /
CB plate on the RH side of the panel. Correct function can be examined by means of two LED´s mounted on
the circuit board, discernible through an opening in the module housing.
Disconnect the control line from the starter relay (located next to the main battery at the foremost ring
frame of the tail boom).
Open and lock the propeller dome to switch the engine bus "ON".
Switch ignition/starter key switch to position "START" and hold in this position:
one red and one green LED must shine simultaneously,
after 3 seconds, the green LED must extinguish,
the red LED must shine as long as the key position "START" is hold.
Unlock the propeller dome.
If the check showed normal function, reconnect control line to starter relay.
If the check revealed malfunction, check lines and connectors. When still not satisfying, the module must
be exchanged.
Never start the engine with a defective ignition retarder module
