WORKBOOK
1002. ENGINE START SYSTEM
The engine start system provides engine rotation and ignition for engine start. A two-position
manual toggle switch labeled STARTER, ON, OFF is located on the starter/ignition control
panel, right-hand subpanel in each cockpit. Placing the switch to the ON position causes
operation of the igniters and engine starter, providing air and spark. The switch must be
manually turned OFF, otherwise the generator will not energize. Electrical command is not
required to activate either cockpit starter switch. Accidental selection of ON with the generator
running will disconnect the generator and cause the MASTER CAUTION and GENERATOR
lights to illuminate. The starter is a 28-VDC, 800-amp motor, located within the same housing
as the generator, but having a separate set of electrical windings. The starter provides initial
rotation of the compressor for engine start and is normally limited to 40 seconds use. Since the
starter develops damaging heat while rotating the compressor, the starter is limited to three 40-
second attempts with a 60-second cooling off period after the first two, and a 30-minute cooling
off period after the third attempt (40 seconds ON, 60 seconds OFF, 40 seconds ON, 60 seconds
OFF, 40 seconds ON, 30 minutes OFF).
1003. LIGHTS
Warning, Caution, and Advisory Lights
The warning, caution, and advisory lights provide a visual warning of malfunctions of aircraft
equipment, unsafe operating conditions, or notice that a particular system is in operation. A test
switch provides for a check of the light bulbs in each indicator. All lights are powered by 28 VDC.
