HID Lamps and Ballast Circuit Diagram

The following file contains detail information about HID Lamps and Ballast Circuit Diagram, available input voltage, maximum input current, power factor, regulation, input watts loss, crest factor. and ballast test (Short-Circuit Current Test, HID Ballast Continuity Testing and Open-Short Circuit Test Limits).

High-Reactance Autotransformer HID Ballast Circuit Diagram

The High-Reactance Autotransformer Ballast is used when the line voltage in insufficient to ignite the lamp using a reactor type ballast. As a result, these ballasts are bigger, heavier, and less efficient than reactor ballasts, but they can be used in a wide variety of applications, because they come with multitap capability.

Reactor Electromagnetic HID Ballast Circuit Diagram

The Reactor Electromagnetic HID Ballast is the simplest, smallest, most efficient and most economical type of electromagnetic ballast. The reactor ballast is electrically in series with the lamp. There is no capacitor involved with the operation of the lamp.

2007 Ford Explorer Sport Trac Passenger Compartment Fuse Panel and Relay

The 2007 Ford Explorer Sport Trac Passenger Compartment Fuse Panel and Relay is located below the instrument panel on the driver’s side. If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components. Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire. The following table and diagram shows detail fuse/relay function and location.
