I NEED TO CHECK IF A WIRE IS GOOD ON A FITNESS MACHINE. HOW DO I KNOW IF ITS GOOD? WHAT SHOULD THE OHMS BE?
any wire, unless it is very long or very thin, will measure zero ohms on an ordinary ohmmeter. But check for continuity does not completely check a cable. Most cables have several conductors in them, so you need to check each one end to end, and check resistance between the wires. Between them, it should measure open or infinite ohms. But the cable could still be bad. Tell us the details please. .
This is true for most wires of practical sizes in devices like fitness bikes or treadmills. If you have a multimeter, you will find there is a setting for reading resistance, which is marked in Ohms. If you set the meter for that setting, you will notice that when you touch the red and black probes together, the meter will read ZERO ohms or close to it. There is a little knob somewhere to set it to zero. Then you can read a wire by touching the probes to the opposite ends of the wire. If the wire is sound, the reading will again be zero (equivalent to touching the probes together). If you don't get zero, the wire may be damaged or corroded. Watch for corrosion, which will give you a high-resistance reading. If the wire is one conductor in a cable with numerous wires in it, you will have to look for the opposite ends of the same conductor. They will probably be color coded, which makes it easier. Good luck.
