What are ballast resistors used for?
A ballast resistor is a device in your vehicle that limits the amount of current in an electric circuit. The ballast resistor is commonly found in older vehicles, because they did not have the benefit of circuit boards found in most of today’s vehicles.
Where are ballast resistors used in ignition kit?
The ballast resistors are often included in the ignition kit of automotive machines such as car engines. Due to its application, such devices are called Ignition Ballast Resistor. Use of this device reduces the risk of coil failure. It is installed in the circuit between the primary voltage source for the ignition coil and the coil stud.
Why do you need a high voltage ballast resistor?
This helps to reduce the coil voltage and coil current, therefore with the addition of the same, the coil does not get as heated as it would without the same, thus increasing the life of the coil. However, during the starting of the ignition engine, a high voltage equal to the primary voltage source is needed.
How big is a ballast resister circuit in a boat?
It can be either a small resistor (often a rectangular white ceramic thingie about 2 inches long) OR in some cases the WIRE that goes to the coil has an intentional resistance to it. The resistance VALUE is often between 1 ohm and 1/2 ohm. Just start by looking for 6 to 12 volts on the coil terminals with ignition on and engine stopped.
What does a ballast resistor do in a florescent light?
After ignition, the alternator begins to recharge the battery, restoring the regular voltage. The ballast resistor then functions to regulate the voltage going to the ignition system to avoid additional wear on the system. Low-voltage lighting systems, such as florescent, LED and neon lights, frequently contain ballast resistors.

Where is the ballast resistor on the firewall?
It is located with the ballast resistor on the firewall. Install it the same way as the resistor. Once it is located on the firewall, connect the positive wire from the ignition to the terminal. With the installation of the ballast resistor completed, start the engine and let it run.
Is there a way to bypass the ballast resistor?
Some customers report that bypassing the ballast resistor by disconnecting the ballast feed wire ( from the starter solenoid or built into the loom) and providing a direct 12 volt feed from the starter solenoid/relay or fuse box to the ignition coil has proved to be a success and has given good results.

How are ballast resistors used in low power loads?
These resistors find application in low power loads like lamps. The resistance of the self varying ballast resistors, on the other hand changes with respect to the current; the resistance increases as the current through it increases and decreases accordingly.
