Use a multimeter and test if there is a voltage drop or current over the wire circuit.
Yes. There is a sign of Speaker/sound on a side DMM. Move the knob of DMM on that symbol. Now connect one prob of the DMM on one circuit element & one under that(If you are designing the circuit on PCB or plain board). If a sound come out of that then it means that your circuit element & the portion below that are properly connected.
A volt meter will do the job.

To test for resistance in a circuit, the circuit should be de-energized.
It depends on what type of circuit board, the symptoms and the application of the board. Otherwise, most technicians will use a good test meter and/or an oscilloscope, or a plug-in diagnostic system (computerized or stand alone).
By using a multimeter
With Hipod leakage current of any circuit (HT Distribution/ Transmission Lines) can be determine and with IR Test insulation resistance between two circuit or parts of machine is determined.
You can run a circuit board test by using a multimeter with the ohmmeter setting. Turn the multimeter to the lowest setting and touch one lead to the tester at the solder point and the other to the socket. The resistance should read 0. A reading of infinity signifies a bad connection and will need to be re-soldered.
You check with an ohmmeter the resistance between the P4-3 and P4-6 pins on the P4 connector on the electronic board.
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
Velim railway test circuit was created in 1963.
mine did that to. my bf had to take off the dash board and test the circuit board but it may be different for u. call a auto store and ask them.
a continuity test is the checking of an electric circuit to see if current flows. That it is in fact a complete circuit.
