INTRODUCTION
Hand signals
P Series Air Carts
It is often necessary to communicate using hand signals in agricultural operations when noise or distance inhibit
communication by voice. The ASAE S351 standard illustrates these hand signals, which provide an easy means of
communication, particularly in the interest of safety.

INTRODUCTION
Basic instructions - Electrical testing - Short circuit to ground
RCIL06PTR021CAA 1
Short circuit to ground occurs when any part of a circuit is in contact with a ground source when it is not intended.
Where the test leads are applied depends on the component or circuit tested:
• When testing a sensor, for example, disconnect the sensor from its connector.
• When testing a controller harness, disconnect the harness at the controller connector and the malfunctioning com-
ponent at its connector on the harness.
• When testing a harness, disconnect the harness connectors at its source and its terminal.
1. Turn system power OFF.
2. Disconnect the connectors for the circuits to be tested.
3. Identify the pins or cavities that need to be tested.
4. Select the resistance setting on the multimeter.
5. Touch one of the test leads from the multimeter to the pin or cavity on one end of the circuit.
6. Touch the other test lead to the pin or cavity on the other end of the circuit.
7. Read the value on the multimeter.
8. The resistance reading should be greater than 100 Ω to indicate an open circuit. If the circuit is not open, the
wire is shorted to ground.
NOTE: The 100 Ω value is a representative value used throughout the diagnostic procedures in this manual. The
expected resistance reading for an open circuit is “infinite” resistance or “open line” on the multimeter. The actual
reading on the multimeter depends on the wire gauge – 0.8, 1.2, 2.0, 3.0 – and the distance between the test
points.
9. Locate and repair the source of the short. Or replace the shorted wire or component.
