Starting with External power source Piper Archer III PA-28-181 step by step,

WELCOME ADVANCE FLYING ACADEMY

STARTING WITH EXTERNAL POWER SOURCE

CAUTION: It is possible to use the ship's battery in parallel by turning only the battery master switch ON. This will give longer cranking capabilities, but will not increase the amperage. Care should be exercised if the ship's battery has been depleted. The external power supply can be be reduced to the level of the ship's battery. This can be tested by turning only the battery master switch on momentarily while the starter is engaged. If cranking speed increases, the ship's battery 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 master switch off.

Starting Engine With External Power Source

CAUTION:

It is possible to use the ship's battery in parallel by turning only the battery master switch ON. This will give longer cranking capabilities, but will not increase the amperage. Care should exercised if the ship's battery has been depleted. The external power supply can be be reduced to the level of the ship's battery. This can be tested by turning only the battery master switch on momentarily while the starter is engaged. If cranking speed increases, the ship's battery 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 master switch off.

Verify that the battery master, alternator switches are OFF, left magneto switch is ON, and all electrical equipment is OFF. Connect the RED lead of the PEP kit jumper cable to the POSITIVE () terminal of an external 24-volt battery and the BLACK lead to the NEGATIVE (-) terminal. Insert the plug of the jumper cable into the socket located on the fuselage. Note that when the plug is inserted, the electrical system is ON. Proceed with the normal starting technique.

After the engine has started, reduce power to the lowest possible RPM to reduce sparking, and turn ON the right magneto switch. Disconnect the jumper cable from the aircraft. Turn the battery master and alternator switches ON and check the alternator ammeter for an indication of output. Check the oil pressure for a positive indication.

DO NOT ATTEMPT FLIGHT IF THERE IS NO INDICATION OF ALTERNATOR OUTPUT.
