Speaker Testing Option 1: Connect a 9 Volt battery to the leads of the speaker, positive lead to positive battery end and negative lead to negative battery end.

-
Speaker Testing Option 2: This option requires the use of a digital multimeter that has a continuity setting.
-
This setting is typically found under the resistance setting but may have its own setting as shown in the picture.

-
-
To test the continuity of the wires themselves and both ends of a single wire and test the continuity.
-
Connect each end of the single wire to the positive and negative leads of the multimeter. If there is an unbroken circuit through the speaker there will be a continuous tone output from the multimeter and/or the meter will not read "OL" (open).

Capacitor Testing: This will require a digital multimeter with a capacitance testing option.
-
Connect the positive lead of the multimeter to the positive lead of the capacitor, and vice versa for the negative. If the capacitor is functioning the multimeter will give a reading that is similar to the ratings given on the capacitor casing.
