Introduction

This guide uses a 9 volt battery and a digital multimeter to test the functionality of the speakers and the wires.

Image 1/2: If a pulse is generated in the speaker then the speaker is still functioning properly. Image 2/2: This same practice would apply to the tweeter speaker as well.
  • 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.

  • If a pulse is generated in the speaker then the speaker is still functioning properly.

  • This same practice would apply to the tweeter speaker as well.

  • Do not keep the 9 Volt battery connected to speaker for an extended period. It could cause damage to the speaker.

Image 1/1: This setting is typically found under the resistance setting but may have its own setting as shown in the picture.
  • 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.

Image 1/1: 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).
  • 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).

Image 1/2: 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. Image 2/2: NOTE: If the capacitor reading is -5% of its given base rating then the capacitor is consider bad.
  • 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.

  • NOTE: If the capacitor reading is -5% of its given base rating then the capacitor is consider bad.
