3.8 Connect the EDC Harness to the P-300M Magnetic Fuel Level Senders:
Route the appropriate fuel level wires (for the number of tanks to be monitored) in the EDC harnesses to the P-300M
magnetic fuel level senders. Cut the wires to length, install the appropriate connectors (see the “Working with
Connectors” section of this manual for more information) and connect to the P-300M fuel level sender.
3.9 Connect the EDC Harness (Volts Measurement Pin) to the Bus:
Pin 35 of the EDC top connector monitors bus voltage. Connect this pin to the bus to be monitored.
3.10 Connect the EDC Harness to the N1 and/or N2 Tach Generator:
Most N1 and N2 Tach Generators provide an output signal on two or three pins. Most often the output signal is
referenced to ground. To connect the EDC harness to the N1 and/or N2 Tach Generator
perform the following:
1) . Determine if the Tach Generator output signal is ground referenced:
Ohm the output pins to ground. If the Ohm reading is less than 200 ohms, the
output signal is ground referenced.
2) .
Connecting the EDC harness to a ground referenced Tach Generator:
Connect the wire from the
appropriate EDC harness to one of the output pins on the N1 and/or N2 Tach Generator. You're Done.
3) . Connecting the EDC harness to an ungrounded Tach Generator: Ground one of the output pins of the
Tach Generator and connect any one of the other pins to the appropriate wire in EDC wire harness. You're
Done.
Note : The Walters Tach Generators have four output pins. Connect the “A” pin to ground and connect
the “B” pin to the appropriate wire in EDC wire harness.
3.11 Connect the EDC Harness to the VI-221's (Voltage Interface Units):
Route the appropriate EDC wire to the VI-221’s that were used to interface the Gear Position Lights, Unsafe Light,
Flap Position, Trim Position and/or any indicator to the EDC.
