PROBLEM
Controller Default
REMEDY
Visually inspect wiring connections of low
voltage control harness to power source and
connections to controller.
Do not insert test
probes into LCVH connectors
.
Inspect battery for low voltage or electrolyte
level. Confirm correct operation of electrical
system. Correct as required.
Inspect connections for leakage. Inspect
tubing for cracks or obstructions. Correct as
required.
Magneto ignition switch must be wired so that
both magnetos are “on” when the switch is in
the “both” position. Consult Figure 6-1 or
ignition switch manufacturer’s manual as
guide.
Connect T-300 SynchroLASAR
®
tool to
magneto. “LEFT TDC” light should turn on
and turn off as magneto rotor shaft is turned.
If “LEFT TDC” light does not turn on, then the
position sensor has failed and needs to be
replaced.
The “LEFT BKR PT” should turn on as the
magneto rotor shaft is turned. If the “LEFT
TDC” does not turn on then the backup relay
has failed and the printed circuit board needs
to be replaced.
Connect T-300 SynchroLASAR
®
tool to
magneto. “RIGHT BKR PT” light should turn
on and turn off as magneto rotor shaft is
turned. If “RIGHT BKR PT” light does not turn
on, then the backup relay has failed and the
printed circuit board needs to be replaced.
If the power source, low voltage control
harness and connections, ignition switch and
magnetos have been inspected and found to
be operating normally, then the controller is
operating in the default mode. Inspect and
replace as required.
Confirm operation of electrical system.
Correct as required.
POSSIBLE CAUSE
No power to LASAR
®
controller.
Low input voltage to
controller.
Faulty manifold pressure
connection from engine to
LASAR
®
controller.
Magneto switch not
configured correctly.
Faulty sensor magneto.
Faulty non-sensor magneto.
Faulty controller.
Engine/airframe electrical
system failure
