How to Use a Ohm Meter or Multimeter to Repair Your Music Gear

In today’s world of music gear sometimes when your favorite ipod or speaker cabinet quits working it’s not convenient to run to the mall or wait around for a UPS shipment. Learning how to use a ohm meter
or multimeter can save time and money.
It’s really not that hard to learn and there is plenty of information online to help you get started. Here’s a good example. How many batteries do you go through and do you ever wonder if it’s the battery that’s going dead or something else?
If you know how to use a multimeter or ohm meter, (they are both the same thing) just put it on voltage reading and touch the probes to both poles of the battery. One meter probe for one battery pole. What does the reading say? If it’s a 9 volt battery it should be close to 9, sometimes as low as the 7’s and some things still work well.
What happens if it says 9 volts and your device still doesn’t work. Well now you know it’s not the battery, check something else. Is there a good connection to where ever the battery plugs in? Yes?
Then switch out something else, like the head phones. Suddenly it starts working. Maybe it’s the head phones are blown or it wasn’t plugged in all the way.
The point is, instead of spending time looking for batteries, you figured out real quick it was something else and saved time and money!
