Being that a voltage regulator passes out a regulated output voltage, the only test we must do to check a 0000008466 00000 n A voltage regulator is a device that takes in an input voltage and regulates it down to the voltage that it is Check the earth connection to the control box, terminal ‘E’. 5 volts, so we should read this output. 0000003289 00000 n Natural Gas Generator. This meter will be able to read the voltage running through your battery and will indicate whether your regulator is working properly. Test the voltage regulator's pin 7 with a voltmeter. If the regulator isn't receiving sufficient voltage, of course it will not be able to output its rated regulated voltage. of course it will not be able to output its rated regulated voltage. Its numerous variations are found in both portable generators and automotive alternators and are described in various patents, such as General Motor's US3376496 for 3-phase applications and Honda's US6522106. Next. Make sure it's working first before you move to the voltage regulator.

So we'll now go through specifically how to test a voltage regulator. 0000002331 00000 n This is why we do this test. If the regulator isn't receiving sufficient voltage, How to Connect a Voltage Regulator to make sure that voltage is, in fact, being supplied to the regulator. Locate the voltage regulator inside the generator's control box. It needs a ground too to operate correctly. The voltage regulator has failed if the voltmeter displays no voltage across the brushes. 0000006264 00000 n The voltage powers the generator motor's brushes for generator ignition and use. Considerations. 3) Check that the Voltage Regulator is grounded. The ground pin is pin 2. Purchase a multimeter. Check that the brown wire between the starter motor and the dashboard ammeter is intact. To sound bona fide, I might as well give you the official job description of the gen-erator. August 15, 2016 / 9367 / 0 comments “ This article will tell you how to test your generator to find out if your generator is bad or if your voltage regulator is bad. Using the voltmeter to check AC voltage while in any other mode will blow the meter's fuse. output a regulated voltage.

Current Regulator.

268 0 obj <>stream %PDF-1.6 %���� the same test as is shown above to see whether it is good or defective. Now that this step is complete, we now read the output voltage.

And This would overheat the generator, so a current regulator is incorporated to prevent premature failure.
