This video covers the essential steps to properly test a car's alternator and diagnose common alternator issues. The guide demonstrates how to check the voltage regulator, diode rectifier, stator, and ...

The load is increased at the test's last stage, including the radio, headlights, and other electrical equipment. The voltage should be at least 13.6 V. Deviation from the norm may indicate alternator ...

A failing alternator can leave you stranded on the side of the road. Here’s how to make sure yours is working properly, with tips from an expert.

A failing battery might seem straight forward to spot, but a failing alternator can be a little more difficult to identify without knowing its voltage output.

The voltage output of an alternator is controlled by the voltage regulator, and usually stays between a constant 13-1/2 to 14-1/2 volts.

The inductive ignition systems should always run an alternator because they are directly affected by the level of input voltage. That means that the output ignition spark at the spark plug is only ...
