How do you test a generator charging system?
How do you test a generator charging system?
Measure the voltage across the battery. Should be about 12.6 volts with the engine off. As the engine speeds up, the voltage should increase to somewhere around 14 volts. If it does, the generator is working and charging the battery.
How do I know if my generator battery is bad?
When the load is applied to the battery, a good battery will drop slightly to around 11.5Vdc but then recover back to normal voltage after a few minutes. A bad battery will drop significantly to a much lower voltage, maybe even 0. This indicates a bad battery and it should be replaced.
How long should a generator battery last?
When maintained properly the common lifespan of a quality battery can be up to three years or 32-5 depending on usage, charging setup and application. To make sure the generator set will start on demand the batteries must be maintained and fully charged at all times.
How can I tell if my generator is charging?
NOTE: These tests are for 12V generators. The same tests will work on 6V generators but the voltages will be roughly one half the 12V values. Is my generator charging? If you have a voltmeter, here are some easy tests to make: Measure the voltage across the battery. Should be about 12.6 volts with the engine off.
What kind of generator did a Chevy truck use?
For 1958-1962 Chevrolet vehicles with air conditioning, a 35-amp generator was used, but trucks were work vehicles and often void of any creature comforts. By the end of 1962, Delco generators were gone from GM except in industrial, farm and marine applications. A good old fashioned 12 volt, 35 amp Delco Generator.
What should I do before changing the voltage on my Generator?
As Memmolo suggested, prior to doing anything else, make sure the generator is working properly and check the condition of the battery. It would be a good idea to check the wiring between the generator, voltage regulator, and the battery as well. The generator should be “polarized” before testing, and after a new voltage regulator is installed.
What should the voltage be on a 12 volt generator?
If it reads 11 to 13 volts, your 12-volt generator is operating correctly; if it’s less than 11 volts, it’s not producing the correct voltage to power your devices, so you need to get it checked professionally. Turn off the generator or car engine once you’ve completed the test. Close the hood of your car if you were testing a car generator.

How does the battery connect to the generator?
The generator field wire, which connects to your voltage regulator from the generator, the generator armature wire, which also connects to the voltage regulator from the generator, and the battery wire, which connects the battery from the voltage regulator. The newly installed replacement regulator solved our issues.
Why does my Chevy truck run when the voltage is off?
We suspected a bad voltage regulator in our vintage truck, because the engine would continue to run when we turned the ignition to the off position. We don’t mean “run-on” like stumbling until it died – we mean RUNNING, like we could leave the key in the off position and drive into town, cruise the boulevard and drive back to the farm.
