Stepper Motor Instrument Cluster | OEM Quality
A stepper motor instrument cluster is an OEM quality instrument cluster that is designed to provide accurate and reliable information to the driver. It is often used in conjunction with other devices, such as a speedometer or tachometer, to provide a complete picture of the vehicle's performance.
The stepper motor instrument cluster is a relatively new technology that has only been in use for a few years. It uses a special type of motor that is designed to move in very small increments. This allows the cluster to provide a much more accurate reading than traditional instrument clusters.
One of the benefits of the stepper motor instrument cluster is that it is much more durable than traditional clusters. The motors are designed to withstand a lot of wear and tear, and they are also less likely to break down. This means that you can expect your cluster to last for many years to come.
How do stepper motor gauges work?
The stepper motor gauge essentially has 2 coils in it while some have 4 coils.
One coil receives power when activated and turns the needle, while the other coil is an electronic positioning device.
The gauge is grounded, and the power coil has 12 volts applied to it.
There's a circuit board attached to the needle positioning coil, and the circuit board is attached to the needle.
When power is applied to the power coil, it causes a magnetic field that pulls (or pushes) the coil back into its original position.
This movement of the needle is what makes everything work. The oil pressure gauge is the only exception.
The stepper motor for this gauge has four coils instead of two. This makes the needle move faster and more accurately, but because it requires more power (and produces more heat) than a two-coil gauge, the oil pressure gauge is one of the last gauges to activate.
The fuel gauge is very similar to the oil pressure gauge. The only difference is that the fuel sender has a variable resistor wired in series with it, so as your gas tank empties, the fuel gauge reads less.

What does the stepper motor do?
Stepper motors use electromagnetism to move the rotor step-by-step. This is a slow process as compared with DC servo motors. But they are much simpler because no feedback mechanism is needed. Also, stepper motors require less power to operate than DC servo motors, so they are often found in battery-operated devices.
Original stepper motors installed in computers were always plugged into the wall to keep them running. This is not because they drew too much power, but rather that they didn't draw enough. They would often lose steps if they run on battery power, and the computer would stop working.
What is a stepper motor on a gauge?
A stepper motor is a type of motor that uses electromagnetism to turn the winding on the rotor. A stepper motor can be used to turn a shaft in a predetermined number of steps. In gauges, this process is useful to move the needle accordingly.
GM instrument cluster gauges use stepper motors. The battery voltage gauge is one example. The fuel gauge is another example, which also has four coils instead of two.
Stepper motors are not as accurate as stepper motors, but they are easy to work with and do not require special tools (such as digital or analog gauges).
How does a fuel gauge work?
A fuel gauge is essentially an ammeter. The more amps the coil in the sending unit draws the lower your gas tank level. Since there's resistance through the fuel pump and battery, there needs to be more current drawn out of the gas tank than the actual amount of amps that is going into it.
The trans temp gauge is the same way, although that's a thermistor instead of a second coil. Fuel level gauges are very simple devices, which is why they can be manufactured cheaply. Old motors used a deflection coil to activate the needle.
New stepper motors do not need any feedback and can be calibrated to read full when they're new. They may lose calibration over time, but it's easy enough to recalibrate them with an ohmmeter.

What is a stepper motor used for?
A stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor is one of a number of related motors used for precise position and speed control. They are typically used in devices such as computer printers and plotters, where the direction and speed of movement need to be precisely controlled.
What does an instrument cluster gauge use?
An instrument cluster gauge uses a step motor and circuit board to operate. It can also use a thermistor or two coils. The stepper motor has a coil attached to it, which makes the needle move along. When power is applied, it moves back into its original position.
What does an instrument cluster use?
An instrument cluster uses many gauges, including an oil pressure gauge and a fuel gauge. A stepper motor is also used for the speedometer and tachometer, while a thermistor is used for the trans temp gauge.
When did GM stop using stepper motors?
GM stopped using stepper motors with their electronic ignition version in 1989. They began to use Hall effect sensors instead of stepper motors because they were more accurate and precise than steppers. Stepper motors are still used in many GM vehicles.
Are all GM Stepper motors the same?
All GM Stepper motors are not the same. Most of the stepper motors that are used on gauges use a standard circuit board, but some use special circuit boards. The oil pressure and fuel sender stepper motors use a different, more efficient design than the basic circuit board. They also use more winding power to operate. A soldering iron that has more wattage power is required to remove these processors.
Can I add a transmission temperature gauge?
Yes, you can add a transmission temperature gauge. The transmission sensor uses the same power and ground as a basic speedometer headlight switch. You need to search for a wire that has 12 volts on it while the engine is running, and use this as the power source. A stepper motor needs 12 volts to operate, so using the same wire is the easiest way. If you don't find a wire with 12 volts on it, simply use the turn signal green wire.
This is usually a good choice since it's already fused, but be careful not to ignore it for too long otherwise the turn signals won't work. Intermittent power failure causing the gauge to malfunction is usually caused by a bad stepper motor or poor ground. You'll need to open the cluster and check the resistance at the stepper motor. Also check to make sure that it is not touching anything, which could short out the resistance.
Stepper motors are very fragile, so if they are ever dropped or mishandled, they will break. When you drop the instrument cluster on a hard surface, it can cause the stepper motor to fall out of its holder, shorting the resistance. One way you can avoid this from happening is by keeping your cluster safe from being dropped.
Stepper motors are pretty fragile, so you should be careful when handling them. Also, always double-check that the stepper motor is securely in place before you put the instrument panel back together.
Where can I get a GM Stepper Motor?
GM stepper motors can be found at most auto parts stores. We also have that available from our shop.
Where can I buy a GM instrument cluster?
You can buy a GM instrument cluster from ISS Automotive. We offer a wide variety of clusters for different GM vehicles.
How much does a GM stepper motor cost?
The price of a GM stepper motor can vary depending on the model and year of the vehicle. You can purchase them new or used. The average cost of a new GM stepper motor is around $100. You can also find them on eBay for less.
A used GM stepper motor can be found for as little as $50. Installation instructions should be followed to avoid damaging the instrument cluster.
Can a stepper motor be repaired?
Yes, a stepper motor can be repaired. A used stepper motor will most likely cost more than $50, so it's usually better to buy a new stepper motor instead of spending money on another used one. Original stepper motors for a GM cluster are costly, but aftermarket stepper motors cost much less.
There's a chance that the stepper motor can be repaired if there is no physical damage caused by dropping or mishandling. If the windings in the rotor are burnt out from an overheat condition, there isn't much you can do to repair it. In this case, you should just get a new stepper motor.
How do I reset my Chevy gauge cluster?
You can reset a Chevy gauge cluster by using the cluster test mode. To activate this mode, press and hold the trip odometer button while pressing the high beam indicator. Hold them both down for around 5 seconds after you hear 3 beeps, then let go of both buttons.
You'll notice that all of the gauges will work at this point, but this is only temporary. The only way to make the cluster stay in test mode is by disconnecting the battery. You can also use a GM service scan tool to reset it back to normal.
What is a stepper motor gauge?
A gauge with a stepper motor is any automotive or marine instrument that uses one. These gauges are also referred to as "analog" because they use an actual needle to point to the measurements on the dial face. A regular gauge simply uses an electrical resistor to indicate measurements on the display, but stepper motors provide much more accuracy than resistors, so they are used in nearly all high-end gauges.
Without a stepper motor, the gauge is unable to provide enough accuracy for measurements. In order to maintain the same level of accuracy as a regular automotive or marine instrument cluster, it would need to incorporate several resistors and an amplifier circuit that would drive those resistors. Even with the addition of a circuit board and resistors, it is still not nearly as precise as a stepper motor.
How do you calibrate a dash cluster?
You calibrate a dash cluster by pressing the trip odometer button when all of the gauges are in their lowest readings. When you press and hold the trip odometer button, all of the gauges should move to their highest readings. This is because a stepper motor actually can't move backward or down in its discrete positions. The only way to calibrate it is by use of an electronic circuit that counts the pulses from the stepper motor. When you release the trip odometer button, all of the gauges should move back to their lowest readings, which means that each gauge has its own specific adjustment. If you're not sure if your cluster needs calibration or one gauge, in particular, is out of alignment, you can use a gauge sweep test to check for this.
You should calibrate the stepper motor in your instrument cluster if all of the gauges are not reading properly, or they're reading too high or too low. If the readings are intermittent while driving, it means that either one or more resistors in your cluster are burnt out, or the stepper motor needs calibration. Since a stepper motor doesn't have a mechanical stop like a resistor does, it will simply overshoot its target.
Original stepper motors installed in a GM instrument cluster cost around $200, but aftermarket stepper motors can be purchased for much less.
Are all gm stepper motors the same?
No, they are not. There are different types of stepper motors used in GM instrument clusters, and each type has its own specific part number. The most common type is the 6-wire stepper motor, but there are also 8-wire and 12-wire stepper motors.
Each type of stepper motor has a different part number, so you'll need to know which type is in your instrument cluster before ordering a replacement. You can usually find this information in the cluster's service manual.
Can a bad instrument cluster cause a battery drain?
Yes. A bad instrument cluster can drain your battery, but it usually won't unless you have a short somewhere in the cluster itself. An exception would be if one of the resistors on the circuit board is burnt out and thus takes up some additional load from your vehicle's electrical system.
Sometimes a resistor on a circuit board will heat up and become loose, which is a sure sign that it's bad. In this case, you should replace the entire circuit board as soon as possible to resolve the problem.
