They are called test leads, you would use them to connect the multimeter to the points that are to be tested.
Use a multimeter and test if there is a voltage drop or current over the wire circuit.
Multimeter test leads can be purchased at specialty stores like Radio Shack or some larger hardware stores. They can also be found online at Amazon and eBay.
You can check if it is shorted, but without coordinating the gate and anode voltages with the cathode, you cannot test a thyrister (SCR) with a multimeter. Check it out of circuit for shorts, then check the circuit, then test it in operation. Anything more advanced will require an oscilloscope.
To verify positive and negative wires with a multimeter, set the multimeter to the DC voltage setting. Connect the black probe to the negative terminal (common), and the red probe to the wire you want to test. If the multimeter displays a positive voltage, the wire is positive; if it shows a negative voltage, the wire is negative. If the reading is zero or close to it, the wire may not be energized.
Yes it is possible to test a diode with a multimeter.

You can test a battery by using multimeter. Set the multimeter to the DC voltmeter setting and then place the leads of the multimeter across the leads of the battery. the multimeter will have a readout of the voltage.
To test frequency with a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter leads to the circuit or signal you want to measure. The multimeter will display the frequency in hertz (Hz) on the screen.
To test power with a multimeter, set the multimeter to the voltage setting, connect the black probe to the ground and the red probe to the power source, and read the voltage displayed on the multimeter screen.
The trailer harness plug should be located behind the rear license plate holder. Some 1997 Chevrolet Tahoe's were not equipped with the trailer harness plug.
To test for power with a multimeter, set the multimeter to the voltage setting, connect the black probe to the ground and the red probe to the power source. The multimeter will display the voltage reading, indicating if there is power present.
To test for continuity in an electrical circuit using a multimeter, set the multimeter to the continuity or resistance setting. Then, touch the probes to the two points in the circuit you want to test. If there is continuity, the multimeter will beep or show a low resistance reading. If there is no continuity, the multimeter will not beep or show a high resistance reading.
Auto parts stores can sell you a trailer harness that plugs in between your existing truck harness. The electrical connection used is usually located behind the rear bumper on the inside of the left frame. Directions will come with the trailer harness kit.
To test a switch with a multimeter, set the multimeter to the resistance or continuity setting. Disconnect the switch from the circuit and touch the multimeter probes to the switch terminals. If the multimeter shows a reading of zero or close to zero, the switch is closed and working properly. If the multimeter shows an infinite reading, the switch is open and needs to be replaced.
To test a circuit with a multimeter, set the multimeter to the appropriate setting (voltage, resistance, or continuity), connect the probes to the circuit's components, and read the measurement displayed on the multimeter. Make sure the circuit is not powered on when testing for resistance or continuity.
To test an LED light with a multimeter, set the multimeter to the diode testing mode. Connect the positive lead of the multimeter to the anode of the LED and the negative lead to the cathode. If the LED is working, the multimeter will display a voltage drop. If there is no voltage drop, the LED may be faulty.
