If the points are not going open when they are open then yes the ballast resistor will get hot and eventually burn out.
Do ballast resistors get hot?
These get hot by nature, as they get hot, they increase resistance to lower voltage to coil to preserve points. No clue what they are for on an ecectronic ignition. 2 or 4 post ballast?
What causes a ballast resistor to overheat?
bad voltage regulator your ballast resistor could be getting too much voltage and smoking the ballast. or it’s not wired correctly… Wrong ballast & or coil combination.
How do you test a ballast resistor?
If the ballast resistor is not working properly, the vehicle will not start. Since it is an electrical system, it is something best left to the professionals to handle. The only way to have the vehicle up and running again is with a ballast resistor replacement.
Why does a ballast resistor get hot?
Check voltage regulator. These get hot by nature, as they get hot, they increase resistance to lower voltage to coil to preserve points.
What happens when a ballast resistor fails?
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. Note: Only use a jumper temporarily to test the ballast.
How do you keep a resistor from overheating?
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.
How many ohms is a ballast resistor?
Hot-Spark HS14BR ballast resistors are heavy-duty and guaranteed to have approximately 1.4 Ohms resistance. For use with 6-volt and 12-volt automotive ignition systems only.
Can you jump a ballast resistor?
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. Note: Only use a jumper temporarily to test the ballast.
What does a ignition coil ballast resistor do?
Generally, an ignition ballast resistor is placed between the primary source of the ignition coil and coil stud. It reduces the failure risk of the ignition coil. When the starter motor cranks the engine, the ignition ballast resistor helps to reduce the coil voltage and coil current.
What happens if you don’t use a ballast resistor?
An ignition system with breaker points will surely suffer from reduced point life if the ballast resistor is removed, as higher amperage can damage the surface of the points causing failure.
How do you protect a resistor from heat?
One of the easiest ways of stopping a resistor heating up is by limiting the amount of power it is subject to. There are many equations for power, but below are some of the most common. To limit the power to a resistor, you can either reduce the voltage or current.
What makes a resistor overheat?
Overheating of Resistor This is due to the voltage attempting to force more current (electrons) through the resistor than it is designed to pass. The resistor will be hot to touch and a faint whiff of burning may be detectable.
More Answers On Should A Ballast Resistor Gets Hot
Ballast resistor getting very hot – For A Bodies Only Mopar Forum
As Dmoore said, at idle it will pick up those electrons and warm up and even get hot, (esp. if you idle a lot) but once you`re cruising it will let the electrons flow and cool down some. You should ohm it out though and make sure it`s the right value.
Ballast Resistor, gets hot yes? | ZCar Forum
The resistor getting warm IS a normal occurance. If you have a voltage source (12 volts) , a complete path for current and difference of potential (any ground will do), current will flow. When current flows, a resistor will do what it is designed to do, resist the flow of current. What that does is cause a voltage drop.
ballast resistor getting hot – W116
Old style Ballast resistors get hot, its the way they work and why they are mounted the way they are. Basically if you were to remove the filler you would find a wire coil, usually a fairly thick gauge and the current flowing through this is creates the resistance. A By-product of this is heat.
Should ballast get hot? – Quora
I could upgrade to LED if I really wanted to without changing the ballasts, except the lights aren’t used long enough that the savings wouldn’t make much of a difference. All in all, to answer your question, if your ballast is magnetic, then yes it will get hot. Otherwise, if it is an electronic ballast, then no, it shouldn’t get hot. 1.6K views

Ballast Resistor Keeps Buring Up????? | The H.A.M.B.
First off, the balist normally gets hot, the longer it is in use, the hotter it gets. That is how they reduce the voltage, they generate heat. New resistors will smoke until the oil on the resistor coil burns off. Unless the resistor coil is touching ground, you need to look elsewhere.
Is the ballast resistor wire supposed to be warm? – JeepForum
Yeah, the Ign Mod should not be getting hot any more because the resistance wire isn’t letting the Ecoil demand 12v. It’s not the coil that’s causing the heated wire, because it’s unaware of the available voltage upstream of the resistor, but the resistance wire still has to suppress voltage, because there is a ground (primary ignition coil …
Ballast resistor is red hot [Archive] – NAXJA Forums -::- North …
The ballast resistor is in effect a primitive voltage regulator. The nature of a resistor of this type is the hotter it gets the higher the resistance, that’s how it regulates the voltage. That 3500 hundred number makes me think O2 sensor. Especially if you get an occasional stumble around the mid RPM range also.
Ballast Resistor: What is it? (And What Does It Do?) | Electrical4U
May 9, 2021A 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. Therefore, an increase in resistance limits the current flowing through the network.
Ballast Resistor -yes/no?? | Hot Rod Forum
Yes you need a ballast resistor between the ignition switch and the (+) post on the coil on points style distributors. Use at least #12 wire for this. In addition run a #12 wire from the (R) terminal on the starter solenoid to the (+) side of the coil. The resistor will get hot but it should not have melted the fiberglass body.

Super hot ballast resistor causes and cures? | For A Bodies Only Mopar …
1……..These DO run “blistering hot.” Normally, you would not put your finger there. That is why they are ceramic 2…….If you have a high turns ratio / performance coil, that can be a factor, as they are lower resistance 3……..If you have a BAD coil AKA “coil starting to go bad” that might explain both the really too hot? and the sputtering
How hot is too hot for a resistor ? – Page 1 – EEVblog
Ceramic core (silicone and vitreous enamel coated) resistors are capable of operating at incendiary temperatures, at least for short periods (say, a few minutes). Ratings of 225C and up are typical. The high surface temperature gives them a much smaller profile for the same power dissipation, and they’re usually not much more expensive. Tim Logged

Very hot fuel ballast resistor! – Comanche Club Forums
Now, add that ballast resistor in series like AMC did. We now have 4.1 ohms of total resistance (3 from the pump, 1.1 from the ballast resistor). The pump is still only supplied the 12 volts DC so the current must go down because the resistance went up. 12 = I*4.1. Divide 12 by 4.1 and you get I = 2.92682 amps.
Ballast Resistor or not? | Jeep Enthusiast Forums
No ballast resistor is necessary with the Prestolite system. The ignition module (the gold box) sends the correct voltage to the coil. Jut and FYI that the Prestolite system really is junk. You would be wise to swap in an HEI distributor, especially since you are rewiring your Jeep.
