Jeremy,
Yes, you should be doing the resistance checks with no power applied.
Inexpensive ohmmeter? Well, if it is a digital multimeter in resistance
mode, you should be OK, but i it is an analog VOM or VTVM, it may not be
showing you the real picture because the voltage may be sufficient to
turn on semiconductor junctions.
