If I didn't have a volt/ohm meter, I'd buy one! <br />Doesn't need to be expensive. I used to buy cheap meters for my techs to use as transistor and diode checking. One with two different battery voltages. People can make a simple tester with a Green or Red LED from Radio Shack, and two resistors wired to leads with clips. The resistor is 3.2K for current limiting, connected in series with one LED. Connect one LED to light red with one polarity, the other with the opposite. Can read voltages at about 1.5 to 2.4 volts depending on LED, can connect with a pair of batteries for checking wire connections or opens.
