Quick Steps To Replace A Ballast Resistor

Here as the current in the circuit varies and increases above a particular threshold value the resistance also starts to increase.

What is a ballast resistor used for. This video explains how the ballast resistor works. Some brands utilized a resistor in the coil or a resistor wire hidden in the wiring from the ignition switch but mopar put their resistor or ballast resistor on the firewall or inner fender. The ballast resistor is a resistor contained in the primary ignition circuit wiring that lowers voltage after the engine is started to reduce wear on ignition components.

A ballast resistor is basically a protective device. A ballast resistor is a resistor inserted into a circuit to compensate for different changes. A resistor that has the property of increasing in resistance as current flowing through it increases and decreasing in resistance as current decreases.

Less well understood is the fact that ballast resistors provide appropriate compensation within a circuit for external demands placed on that circuit. A ballast resistor is used in a circuit to limit the current and hence prevent it from over current faults. The ballast is a fixed resistor with usually two center taps and the fan speed selector switch is used to bypass portions of the ballast.

Wordnet search defines a ballast resistor most commonly found in an automobile ignition system as a device inserted into a circuit to compensate for changes such as those arising from temperature fluctuations. Others might give a different answer to the question what is a ballast resistor like this. Certain devices such as fluorescent lamps can exhibit a quality known as negative resistance where an increase in current can result in a decrease in voltage.

A ballast resistor is an electronic component that is often used to regulate the current in a circuit. Another common use of a ballast resistor in the automotive industry is adjusting the ventilation fan speed. Over time the ballast resistor can be damaged by normal wear and tear so there are a few things to look for when you suspect a bad or failing ballast resistor needs servicing.

The ballast prevents extreem current from flowing typically during startup conditions examples requiring ballast resistors are florescent lamps older car coils vacuum tube circuits hvac fans. The ballast resistor is commonly found in older vehicles because they did not have the benefit of circuit boards found in most of todays vehicles.
