This is use to locate the ground fault of a single cable. This test is performed with the aid of a low voltage supply with an ammeter or voltmeter. In this test the resistance between one end of the cable C1 and the earth is first measured with the other end, C2 isolated to earth and then with the C2 earthed. Let the two readings be represented by R1 and R2 rep! If r1 and r2 are the conductor resistance of the length of cable at C2 to fault and at C1 to fault rep!, and "r" is the resistance of the fault to earth
You use an ohm meter to check for continuty, low ohm reading, on the center pin between the two ends of the cable. You would then check for continuity between the shield, or outside connector. If both of those are good, you should also check between one of the center pins and the shield to ensure their isn't a short on the cable.
It provides stability in case of problems with disconnectors auxiliary contacts (stuck contacts or wiring problems). Ir relies on the feeder currents in the busbar. Disconnectors positions are not required. There is no selectivity using check zone. It's usefully because it prevents external faults to be considered as a busbar fault.

Check digits are determined (or derived) by a set algorithm using the digits of the account number.
Usually a megaohmeter (or megger) is used to test high current feeder wires for ground faults before they are landed on a transformer.
Cleanliness, sturdy, faults
First check and see if there's any voltage on the cable by using a voltmeter and then use an ohmeter to check for resistance to ground.
Verify tip & ring pair balance (one side is not longer than the other which makes the line noisy), check for continuity (both conductors are unbroken from end to end), no shorts or ground faults.
Set the meter to ohm function. then put the leads on either end of the cable. it should read 0 if its good infinite if its bad
Check your cable. If you are using a universal component cable, and the switch on the cable is set to video, you will get only black and white on the Wii. Flip the switch to component and your problem may vanish - mine did.

Check the tail light bulbs, clean it if you have using fine sandpaper. If it did no work check the cable connected to the lights. If the cable integriry was not damaged, check the fuse box.
Check the battery, check if it is broken, check if it is the right remote and though it is a rare case check if it is your cell phone that you try to switch on the cable.
