PIPER CHEROKEE WARRIOR SERVICE MANUAL
2-2 1 a . O P E R ATION OF EXTERNAL 28 VDC POWER RECEPTACLE: On the PA-18-161, Warrior III,
S / N 's 2816110 and up, the 28 Vdc external power receptacle is located on the right side of the fuselage just aft
of the baggage door.
When using 28 Vdc external power for starting or operation of any of the airplane's equipment, the
following procedure should be followed:
a. Turn aircraft BATTERY switch, ALT E R N ATOR switch, and all electrical equipment OFF.
b . Insert the plug of a 28Vdc power supply into the MS3506-1 receptacle located on the aircraft
f u s elage.
During engine start, it is possible to use the ship's battery in
parallel by turning only the BATTERY switch ON. This will
give longer cranking capabilities, but will not increase the
amperage. Care should he exercised, because if the ship's
b a ttery has been depleted, the external power supply can be
reduced to the level of the ship's battery. This can be tested by
turning only the BATTERY switch ON momentarily while the
starter is engaged. If cranking speed increases, the ship's
b a ttery is at a higher level than the external power supply. If
the battery is at a lower level than the external power supply,
continue starting with the BATTERY switch OFF.
c. Proceed with NORMAL engine starting technique.
d. After the engine has been started remove the jumper cable plug from the aircraft.
e . Turn the BAT T E RY switch and ALT E R N ATOR switch to the ON position. Check the alternator
ammeter for an indication of output. Do not attempt any flight if there is no indication of alternator output.
2-22. CLEANING.
2-23. CLEANING ENGINE COMPARTMENT: Before cleaning the engine compartment, place strips of
tape on the magneto vents to prevent any solvent from entering these units.
a. Place a pan under the engine to catch waste.
b. With the engine cowling removed, spray or brush the engine with solvent or a mixture of solvent and
degreaser, as desired. It may be necessary to brush areas that were sprayed where heavy grease and
dirt deposits have collected in order to clean them.
Do not spray solvent into the alternator, starter, vacuum pump,
air intake, and alternate air inlets.
c. Allow the solvent to remain on the engine from five to ten minutes; then rinse the engine clean
with additional solvent and allow to dry.
Do not operate engine until excess solvent has evaporated or
otherwise been removed.
d. Remove the protective covers from the magnetos.
e. Lubricate controls, bearing surfaces, etc., per Lubrication Chart.
