The Pertronix Ignitor Ignition System doesn’t care at all if there is a Ballast resistor in the car or not. Period. If your COIL requires one, leave it in the car. Pull the 12V (RED wire of the Ignitor) from the input side of the Ballast, so it gets the full voltage.
Does the PerTronix flamethrower coil need a resistor?
If you have the 1.5 ohm coil you can use the resistor wire. Petronics recommends to use the . 6 ohm coil with 12 volts and the Igniter 2 which solved problems that the original set up had.
Do you need a ballast resistor with electronic ignition?
Electronic ignition systems, whether factory Mopar or aftermarket, don’t utilize breaker points, thereby not actually needing a ballast resistor to control amperage through the pickup coil.
Do I need a ballast resistor with PerTronix and MSD coil?
Pertronix setups still need a resistor unless you run there coil (which probably has one built in already) Its just you have to wire the pertronix box to have a full 12 volts so you cant run it off the resistor wire feeding the other brand of coil.Why do ignition coils need ballast resistor?
A Ballast Resistor is an electrical device that reduces voltage to the coil so that more energy is available for the spark plugs during starting. Why would a Ballast Resistor be fitted in a car? … To counteract this distribution of energy, ignition systems were changed to use a 9v coil instead of a 12v coil.
Do I need a ballast resistor with MSD distributor?
Basically you need to have a ballast resistor on your setup thats why MSD has it in there instructions. The resistor is so you dont blow up the coil when the power is on. Doesnt matter points or electronic. Yes points need a little more resistance so there resistor has more ohms.
Which PerTronix coil do I need?
The 3.0-ohm coil should be used on PerTronix Ignitors installed on four- and six-cylinder engines while 1.5-ohm coils should be used for eight-cylinder applications. These coils can be used on virtually any inductive (non-capacitive discharge) ignition system.
Does MSD coil increase horsepower?
No, unless they’re somehow defective as installed. If you’re asking if aftermarket coils installed in a stock engine will increase horsepower, or reduce emissions, or increase gas mileage, or make the engine run smoother, the answer is no.Do I need a ballast resistor with MSD ignition?
Late-model electronic ignitions or an MSD Ignition do not require the ballast. If you are looking to upgrade your stock coil, or want to compliment the performance of your MSD Blaster Ignition, MSD 5, 6, or 7, the Blaster Coil line is the right choice. Our Blaster Coils are designed for improved spark output!
Can you bypass a ballast resistor?The duty of the ballast resistor is to limit voltage to the ignition coil. … A quick and easy way to diagnose ballast resistor failure is to bypass it by running a temporary jumper wire from the battery to the coil. If it starts and remains running, you’ve found the problem.
Article first time published onHow do you tell if a coil needs a resistor?
To test your ballast resistor you need an ohm meter or multimeter set to ohms. Remove the connectors from both sides of the resistor. The ohms should read between 1.8 and 5 ohms. You should be getting 9 volts to the positive side of the coil.
What are the symptoms of a bad ballast resistor?
- Vehicle starts, then immediately dies. The most obvious symptoms will be the vehicle starts, but then immediately dies as soon as you release the key. …
- Not starting at all. …
- Don’t jump the resistor. …
- Let the vehicle be.
What are ballast resistors used for?
A ballast resistor is used in a device to compensate for changes and secure the other components of a network. When the current flowing through the resistor increase, the temperature also increases. And due to the temperature rise, the resistance also increases.
What is ballast resistor?
What is a Ballast Resistor? A ballast resistor is used in a circuit to limit the current and hence prevent it from over current faults. Here, as the current in the circuit varies and increases above a particular threshold value, the resistance also starts to increase.
What causes a ballast resistor to fail?
The resistance through the ballast resistor varies with current flow which varies with engine rpm. This naturally causes the resistor to expand and contract from heat. That’s why they eventually fail.
What is the gap on a PerTronix Ignitor?
The Ignitor has no set specification in which the spark plugs should be gapped at. Every engine responds differently to spark plug settings. In most cases increasing the factory recommended gap by . 005 improves the engine performance, but we cannot know all the parameters of your engine, so it is entirely your choice.
What wattage should I vape 1.5 ohm?
For instance if you use a 1.5 ohm coil then you can get away with anywhere between 8-16 watts, but a . 5 ohm coil needs between 15-30 watts to give you the right amount of power.
Do PerTronix igniters go bad?
Gone but never forgotten If a “pert” is a Pertronix Ignitor, yes, they have great reliability. The one in my son’s car has been in use for 4 years, the one in my daughter’s car for the 5 years we’ve owned the car, and who knows how long before us (it was in there when we bought it).
How does the Pertronix ignitor work?
“The points operate mechanically with a rubbing block that rubs on a small cam in the distributor. This rubbing block wears, which changes the timing and the point gap, altering both the performance and the amount of spark available,” Don explains.
Does a Blaster 2 coil need a ballast resistor?
blaster two Yes, you must have a ballast resistor.
Are aftermarket ignition coils good?
Aftermarket ignition coils are never worth the extra few bucks in savings. In a few cases, you can get away with using a cheap universal aftermarket part as long as it doesn’t affect: The engine’s performance. The vehicle’s safety.
Do aftermarket ignition coils make a difference?
A high performance ignition coil helps engine performance four important ways. First, the higher voltage allows for a larger spark plug gap, which results in a more robust initial flame kernal at the start of combustion. The result is a real-world engine torque increase.
Do coil packs improve performance?
In addition to being more reliable, coil packs are generally credited with providing more horsepower and torque than a common distributor. Because a coil pack generally creates a much more efficient spark, it also known to provide a slight fuel efficiency improvement over vehicles that use standard distributor caps.
Can you hook up a ballast resistor backwards?
Resistors lack polarity. There is no backwards.
How do you connect a coil to a resistor?
Strip the end of the positive wire from the ignition, and connect it to the positive end of the resistor. From the other terminal on the resistor a wire goes to the positive on the coil. Make sure to attach securely to the connecting terminal, by wrapping the wire around the post and tightening with a screwdriver.
What effect does the open circuit have in the primary circuit on the ignition system?
When the points open and close it triggers the primary ignition circuit, which in turn fires the coil. Inside the distributor, there is something called the rotor which rotates and deliver the spark to the correct spark plug wire which ignites the spark plug.
What's the difference between a ballast and non ballast coil?
A ballast coil is designed to produce the same spark output, but with only 6 to 9 volts on the input. With a non-ballast coil, the input to the coil is the same, 12 volts, whether the engine is running, or being cranked by the starter motor.
Does HEI distributor need ballast resistor?
When using HEI, the distributor requires a 12 volt feed. In order to achieve this the ballast resistor or the resistance wire must be removed from the circuit and replaced with a pure 12 gauge feed wire. … This means that there is no power on the “RUN” circuit when the ignition switch is in the “CRANK” mode.
How many volts should my coil have?
The electrical system in your vehicle works on 12 volts, so every component must be based on 12 volts, as well. There is a wire connected to the ignition coil (known as a “hot wire”) that carries the 12 volts into the coil itself.
Can a resistor fail?
Resistor failures are considered to be electrical opens, shorts or a radical variation from the resistor specifications. The failure modes experienced vary with the type of construction. A fixed composition resistor normally fails in an open configuration when overheated or overly stressed due to shock or vibration.
How do I know if my headlight ballast is bad?

- Strange Sounds. …
- Headlights Not Working. …
- Changing Light Colors. …
