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.
If the battery warning light (a light in the shape of a battery symbol) on the dashboard comes on while you're driving, that means the charging system isn't working, but the fault may lie in something other than the battery. The cause of the battery light could be a loose or corroded battery cable or other wire connecting components of the charging system, or it might be a problem with the alternator or voltage regulator. The alternator generates the power that is stored in the battery. If the alternator fails, or the accessory belt that drives the alternator is loose or broken, then you'll end up with a dead battery because the bad alternator isn't recharging the battery.
