Description
The starters are relay-controlled and are actuated by rotary
type,
momentary-on
switches
incorporated in the
magneto/start switches located on the pilot's subpanel. To
energize the starter circuit, hold the magneto/start switch in
the START position. After starting, release the switch to
the BOTH position.
The warning light placarded STARTER ENERGIZED
(serials TH-1194 and after) will illuminate whenever
electrical power is being supplied to either the left or right
starter. If the light remains illuminated after starting, the
starter relay has remained engaged and loss of electrical
power may result. The battery master and both alternator
switches should be placed in the OFF position if the light
remains illuminated after starting. If the light does not
illuminate
during
starting, the
indicator
system is
inoperative and the loadmeters should be monitored to
ensure that the starters do not remain energized after
starting. This light can be tested by the TEST-WARN
LIGHT switch, located on the floating instrument panel.
EXTERNAL POWER
The external power receptacle is located in the outboard
side of the left nacelle and accepts a standard AN type plug.
The power unit should be capable of delivering at least 300
amperes for starting. Before connecting an external power
unit, turn the electrical systems and avionics off to avoid
damage due to electrical surges. When external power is
I
connected, the battery switch should be turned on. If polarity
is reversed, a diode in the coil circuit will prevent contactor
operation.
