How does an alternator work?
•If the alternator output voltage is below 14.5 volts, the voltage regulator responds by increasing current through the field coil of the rotor. This causes the voltage to increase. •A charging current is sent to the battery. The windings in the stator generate a voltage, and a charging current is sent to the battery.
How do I know if my alternator is AC or DC?
In use, 1 millivolt equals 1 amp. Dealing with millivolts is much safer than dealing with amps. To identify an alternator system, inspect wire or wires that come from under or behind the blower housing. A single wire with no diode is generally, but not always, an AC only system A single wire with a diode is generally a DC only system.
How do you check if a Briggs & Stratton alternator is good?
If the battery and AC output are OK, replace the regulator/rectifier by process of elimination. AC tests are made for AC volts while tests for DC charging output are made in DC amps. One or both will be used to check the health of all Briggs & Stratton alternator systems.
Can I Witness The tests carried out on my alternator?
In line with IEC 60034-1, additional post production tests may be carried out, as requested by the customer at the time of alternator order. Documented results will be despatched with the alternator. It is also possible for the customer, or his representative, to witness the tests carried out on his alternator.
