5.
Note the position of the propeller. Rotate the propeller in the normal running direction
(CW as viewed from cockpit) through two complete revolutions while observing the
Test Indicator LEDs. Notice the indicators switching ON and OFF as the holes in the
camshaft intersect the sensors.
6.
Use a TDC locator to find TDC on Cyl #1. Observe the FADEC Timing Tool LEDs;
the N
c1
LEDs should “blink” at approximately 11° BTDC.
NOTE: Channel 2 (N
c2 /
N
e2
) and Channel 3 (N
c2 /
N
e2
) LEDs will
illuminated approximately 5 degrees after Channel 1 (N
c1 /
N
e1
).
7.
Slowly rotate the propeller clockwise while observing the tester LEDs.
a.
The N
c1
LEDs will blink once in two propeller revolutions just before TDC.
b.
In two propeller revolutions, the N
e1
LEDs will blink 11 times.
8.
If the newly installed SSA fails to pass this operational check:
a.
Troubleshoot the sensor head. Refer to the section “Speed Sensor Assembly
Troubleshooting” in Chapter 8, Troubleshooting.
b.
Remove and replace the SSA (refer to the TCM overhaul manual (OH-24) for
SSA removal; installation and timing and instructions). Repeat the operational
check.
9.
If the SSA passes the operational check, install the engine low voltage harness 25-pin
connectors according to instructions in 10-6.1.
10.
Clean, gap and install the spark plugs with new copper gaskets. Refer to “Ignition
System Maintenance” in Chapter 9 of this manual for spark plug installation and high
voltage harness connection instructions. Torque the spark plug and high voltage
harness according to Appendix B specifications.
11.
For proper operation of the engine, route, clamp, support, and protect the wires in the
engine low voltage harness in a manner to prevent chafing, fretting, and wear of the
lead wires. Route and secure the harness according to Appendix C, “Harness
Routing” Instructions.
12.
Perform a “FADEC Level I Diagnostics” in Chapter 8, Troubleshooting of this
manual to check the FADEC System. If the FADEC System fails this diagnostic
check, troubleshoot the system until the malfunction is corrected.
13.
Perform an “Engine Operational Check” according to the instructions in Chapter 6,
Operational Performance Checks.
