Turn it on... Does it work ?
Yes - job done
No - Bummer!
If there is an electric short, the resistance of the circuit would be zero. So you can use an ohm meter to test it.
To test a motor, use a megger (megohm meter) to test the insulation of the internal motor windings. Select a voltage to apply to the motor using an output from the megger that is higher that the operating voltage that the motor operates on.
Yes, test with a electric multy meter
A megger is used to test the resistance of high voltage cables, insulation and motor windings. The test employs a megohm meter.
Electric motors do not produce electricity, they use electricity, and convert that energy to another form of energy, that we measure in horsepower. See related links.
Even if you know how to reconnect it safely, you can probably be charged with theft if you reconnect it without authorization. Whatever the reason it was disconnected, the electric company may want to inspect or test the connected wiring to be sure it is suitable condition to be reconnected. You will not likely be authorized to connect it yourself. Likely only electric company personnel or a licensed electrician would be authorized.
meter electrical meter VOM - stands for Volts/Ohms Meter test your bulb with an Ohm meter
Bad motor -see if you are getting power to it - if so bad motor Bad switch- jump wires to test
The first step is finding what the issue is. Check the fuse to the motor. If you have access to a volt meter or test light, check to make sure that the motor is getting power when the switch is on. If power is there then the motor needs to be replaced.
You use a device called a megger or meg ohm meter. Have the voltage range of the megger set to the working voltage of the motor. The first test should be to ground. One lead on the frame of the motor , the other lead one of the 6 wires. Test all 6 wires. If no ground shows up, test the individual coils against one another. If the coils are not grounded together, the motor is safe to energize.
Start with the electric motor. Use a jumper wire on the positive wire of the motor and a hot wire. Does it work? If so, then you have to test the wiring harness back to the relay/fuse, the activation switch, and the battery. If the motor didn't work, then you need to replace the motor. If the motor works, but the top doesn't, then you need to check for broken cables or binding in the roof structure.
usually what causes that is the blower motor resistor. Get a volt meter and test it according to it's values, 90 percent of the time it's the RESISTOR.
