EXTERNAL POWER RECEPTACLE.
OPERATION OF EXTERNAL POWER RECEPTACLE.
The external power receptacle is located on the right side of the fuselage aft of the wing on the PA-28RT-
201T and just aft of the firewall on the right side of the fuselage for the PA-28RT-201. When using external
power for starting or operation of any of the airplane's equipment the following procedure should be followed:
1. Turn aircraft MASTER SWITCH to OFF position.
2. Ensure that the RED lead of PEP (Piper External Power) kit jumper cable is connected to the
POSITIVE (+) terminal of the external 12-volt battery and that the BLACK lead is connected to the
NEGATIVE terminal.
3. Insert the plug of jumper cable into the socket located on the aircraft fuselage.
4. Turn the aircraft MASTER SWITCH ON and proceed with NORMAL engine starting technique.
5. After the engine has been started, turn the MASTER SWITCH to the OFF position and remove the
jumper cable plug from the aircraft.
6. Turn the aircraft MASTER SWITCH to the ON position and check the alternator ammeter for an
indication of output. (DO NOT ATTEMPT ANY FLIGHT IF THERE IS NO INDICATION OF
ALTERNATOR OUTPUT.)
If aircraft battery is weak, charging current will be high. Do not
take off until charging current falls below 20 amps. Do not take
off with a completely discharged battery as three-volts is needed
to excite the alternator.
