To test for resistance in a circuit, the circuit should be de-energized.
Testing of an electrical circuit for voltage requires the supply to be energized.
power test
A cable tester is used to test the electrical connections in a cable or other wired device. There are two ways to test for a connection: continuity test and resistance test. A cable tester can also test for a short by determining voltage.
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
This can absolutely cause the drain. If the solenoid happens to be stuck in an energized position the battery will slowly drain. A Good Way To Test++++Get A Light 12 Volt, Or A Voltage Tester From Parts House==Looks Like A Screwdriver, With A Wire Running Out Thr Top & Sharp Pointed On The Other End. Remove Your Ground Cable Connect Tester To Ground Cable, Then Connect Other End To Neg. Terminal ( This Will Be Between Ground Cable And Battery, Leave Hot Cable Connected. DO NOT TEST THROUGH IT. THE POSITIVE CABLE IS NOT REQUIRED FOR THIS TEST. IF YOU HAVE A VOLTAGE LEAK THE LIGHT WILL COME ON !!! IF IT DOES CHECK DIFFERENT ITEMS< WHEN THE LIGHT GOES OUT> YOU GOT IT.
Start the car and while it is running, disconnect the positive cable from the battery. If the car stalls, the alternator is bad.
Some of the steps for doing a cable modem speed test, include properly configuring the cable modem so that its running optimally, and using a speed test website to test the speed of the modem.
Yes, you can.
One can test their cable internet connection online at the website Speed Test. One may also check their connection at Speak Easy, Test My Speed and Ping Test.

You can test the speed of your cable internet. Cable providers usually provide a link to test your speed and there are several other options online that offer that service. I personally have used Speednet to test my internet speed and was pleased with the results that I got.
