When it comes to testing for neutral safety, there are a few different methods that you can use. The most common method is to use a voltmeter. You'll want to set the voltmeter to the ohms setting, and then place the probes on the two terminals of the neutral safety switch. If the voltmeter reads infinity, then the switch is good. If the voltmeter reads zero, then the switch is bad.
Another way to test for neutral safety is by using a continuity tester. This is a similar process to using the voltmeter, but you'll be using a continuity tester instead. Simply place the probes on the two terminals of the neutral safety switch, and then see if the continuity tester lights up. If it does, then the switch is good. If it doesn't, then the switch is bad.
Finally, you can also test for neutral safety by using a multimeter. To do this, you'll want to set the multimeter to the resistance setting, and then place the probes on the two terminals of the neutral safety switch. If the multimeter reads infinity, then the switch is good. If the multimeter reads zero, then the switch is bad.
No matter which method you use, testing for neutral safety is a relatively simple process. By using one of the above methods, you should be able to easily determine whether or not your neutral safety switch is working properly.
