The charging system has been required as long as we have had a need for an electrical system and from research it’s been since the requirement of horns in motor vehicle in the early 1900’s. An alternator is a voltage generator that uses mechanical energy to rotate a set of magnets within a field of windings called a stator. The alternating current (AC) voltage created by the spinning magnetic field is converted into a usable direct current (DC) voltage with a rectifier and then regulated by a voltage regulator so that the voltage level in the electrical system stays within a specific operating range. The alternator provides all the voltage needed to operate a vehicle, the battery is only used as a reserve for heavier load conditions, as a voltage source for the engine starting system, and to supply a small amount of voltage to the electromagnets in the alternator which boosts the magnetic field in the alternator and increases voltage output.

Product Features:

• Application matched components ensure the charging system can be returned to like new condition.

Product Features:

• Our Throttle Position Sensors maintain specific installed outputs to match OE rather than adjustable consolidated designs
• Circuits are printed on flexible polyimide film or ceramic-based substrates for excellent dimensional stability preventing electrical performance drift. Noble palladium/gold/platinum alloys provide low contact resistance for extended service life
• Each TPS uses integral rotor bearings and return springs for easy installation
• Each sensor undergoes rigorous end-of-line testing with thousands of data points to validate output voltages for optimum performance and trouble-free operation

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

Product Features:

• CarQuest electrical connectors meet or exceed OE wire gauge, insulation, and terminal material requirements.
