The test procedure is quite simple. Set the meter to read DC volts, and set the correct range if needed. Some meters will select the correct range automatically. Nearly all meters will come with instructions on how to set them to read DC volts. Next, connect the meter across the vehicle battery, positive (+) to positive (+) and negative (-) to negative (-). With the engine running at a moderate idle - say 1200 to 1500 RPM, the meter should read approximately 13.8 to 14.8 volts and be steady. If the reading is substantially outside these figures and all other items mentioned have been tested and verified good, then the alternator is likely defective.
Analog electric motor checker - This highly portable vehicle diagnostic tool is necessary in the repair and maintenance of three-phase machines. A technician will also use this auto diagnostic tool prior to installation to make sure that circuitry is completely sound. Some of the faults that it helps in detecting include: Open circuits, Loose connections, Faulty installations, Rotor flaws, Short circuits. All the above mean that electricity is either flowing inefficiently in the system or not at all. If not detected early on and fixed, the entire machine will deteriorate at a faster rate meaning that more expensive repairs and replacements will be needed.
