Generators are the best option as they do the best job when it comes to lighting homes. Even a tiny amount of this residual magnetism can generate a small portion of electricity. This video is a how-to on recharging a generators field with a corded electric drill. If a generator lost its residual magnetism, it should be excited separately i. e. from an external power source up to gaining the essential magneti Remove the wires going to the brushes from the regulator, set up some wires or jumpers to a B+ (12VDC) source, usually your starting battery, and put a voltmeter on the output. Many-self excited generators do exactly that. This cycle continues until the generator produces its rated power (after a very short period of time, usually by the time the engine has spun up to normal operating speed). How does this happen? It's energy efficient with its Generac G-Flex Technology that allows it to provide only as much power as is necessary to the home, and thus use less fuel. 1. Generator Parts; Onan ; Voltage Regulators ; Volt. To restore the small amount of residual magnetism necessary to begin voltage buildup, connect a 12 volt battery to the exciter field while the generator is at rest, as follows: Remove exciter field leads F+ and F- from the voltage regulator. Though it is a loss of residual magnetism to a generator pole the. Generators have complex control circuits, and any fault can interfere with the power supply.
