Tracker EV Clicking When Accelerating: What It Means and How to Fix It
Share
You press the pedal on your Tracker EV and instead of the quiet hum that normally follows, a click cuts through the silence. Maybe it happens once, maybe it repeats on every ride and either way, you want to know the cause and whether it is safe to keep driving.
Tracker EV clicking when accelerating is one of the most commonly reported problems on this platform, and one of the least accurately addressed online.
Most content out there covers mainstream consumer EVs or gas-powered machines. It rarely applies to the Tracker EV's specific electrical and mechanical setup.
When the Tracker EV makes a clicking sound when accelerating, the cause is almost never what generic forum posts suggest.
This guide covers the real causes, walks through a structured home diagnostic process, and gives you a clear framework for deciding what to do next.
Why Does the Tracker EV Click When You Accelerate?
The Tracker EV runs on a 72-volt electric drivetrain. When you press the accelerator, a sequence happens fast: the contactor relay activates, the main solenoid closes the high-voltage circuit, current flows to the motor controller, and the drivetrain engages.
Any weakness in that chain can produce a click. Electric UTVs run so quietly that a noise which would go unnoticed in a gas-powered vehicle stands out immediately.
That does not automatically mean the fault is serious, but the cause needs to be found.
The Tracker EV clicking noise when accelerating can come from two separate systems. The electrical side includes the contactor relay, main solenoid, and wiring connections. The mechanical side covers the CV axle, wheel bearings, and axle splines.
Many Tracker EV owners notice the clicking sound under load first, on an incline or with weight in the bed, before it becomes consistent on flat ground.
Matching the click pattern to the right system is what separates a quick fix from an unnecessary parts order. If what you are hearing leans more toward a rattle or a thud, the bad boy buggy weird axle noise guide helps sort those symptoms before this diagnostic process goes further.

The Most Common Causes of Tracker EV Clicking When Accelerating
Once you have matched your click pattern above, here is what is actually happening inside the vehicle and what it means for the repair.
Faulty Contactor Relay: A Top Cause of Tracker EV Clicking When Accelerating
The contactor relay is the most overlooked source of this problem. Its job is to send the control signal that allows the main contactor to close and route power through the 72-volt system.
When it starts to fail, the relay can click or chatter at the exact moment the pedal is pressed, because that is precisely when it is called to activate.
Many owners move straight to the solenoid and skip the relay entirely. That results in unnecessary part swaps and the same noise returning within days.
Symptoms to watch for:
-
Click at the moment of pedal press, not during steady movement
-
Brief hesitation before the vehicle responds to the accelerator
-
Vehicle turns on normally but pauses before it moves
Research on contactor failure in electric vehicles confirms the issue goes beyond noise. A faulty contactor can cause battery drain, unpredictable system behavior, and heat buildup in the surrounding electrical components.
Catching it early prevents secondary damage to connected parts.
Fix: Replace with an OEM-compatible contactor relay matched to the Tracker EV or related Bad Boy Buggies platforms.

Worn or Failing Solenoid
The main solenoid is the high-current switch that connects battery power to the motor. On the Tracker EV's 72-volt system, solenoid wear is a documented issue, particularly in vehicles that see regular off-road use, moisture exposure, or extended time on aging battery packs.
Before replacing any electrical part, check the terminal connections first. Corrosion at the battery posts or solenoid terminals can produce the exact same symptoms as a failed solenoid and costs nothing to inspect.
Confirming the fault takes a basic multimeter. With the key on, check voltage at the solenoid input terminal. A healthy system reads close to 72 volts. If the input reads correctly but the output drops to zero when the pedal is pressed, the solenoid is the problem.
Symptoms to confirm:
-
Click when the accelerator is pressed, with no corresponding vehicle movement
-
Intermittent loss of drive, particularly under load or on terrain
-
Voltage gauge flickering or dropping during acceleration
CV Axle or Wheel Bearing Wear
Mechanical clicking follows a different pattern from electrical clicking, and separating the two is what directs the repair correctly.
Electrical clicking is tied to the pedal press and occurs at the same moment every time. Mechanical clicking is rhythmic and tied to wheel rotation speed. It changes as the vehicle moves faster or slower, and it shifts during turns or on uneven terrain.
A worn CV axle produces a clicking or popping sound that becomes most noticeable under load or through a corner. When the protective boot tears, grease escapes and debris enters the joint.
That contamination works into the internal ball bearings and produces a rhythmic noise that gets worse with continued use.
Wheel bearing failure has a different character. A worn bearing produces a constant humming or growling sound that rises with vehicle speed. Unlike CV noise, it does not change sharply when the accelerator is pressed, but shifts as vehicle weight transfers during a turn.
From a technical standpoint, early-stage CV wear is one of the most preventable failures on electric UTVs. A torn boot caught before the grease fully escapes can often be resolved with a boot replacement rather than a full axle swap.
If the sound shifts toward a pop on tight turns, the bad boy buggy popping noise when turning resource covers how to separate those two symptoms before a repair decision is made.

Loose Wiring or Connector Issues
This is the first place to check because it takes under five minutes and costs nothing.
Loose wiring in the accelerator circuit can produce intermittent clicking that closely mimics solenoid or relay failure. On a vehicle used on rough terrain, the wiring harness can snag on debris and shift a pin slightly out of its housing without fully disconnecting.
Where to inspect:
-
The four-pin accelerator wiring plug under the pedal assembly
-
Terminal connections at the battery and solenoid
-
The wiring harness routing beneath the chassis for chafing or exposed wire sections
Fix: Reseat connectors firmly, tighten terminal hardware, and check the harness for any sections that show rubbing or damaged insulation.

How to Diagnose Tracker EV Clicking When Accelerating at Home
You do not need professional equipment to identify the source of the Tracker EV clicking sound. This process takes under 30 minutes with a basic multimeter.
A separate industry survey found that 85% of DIY vehicle owners run their own diagnostic check before visiting a shop, to confirm whether a repair is within their reach.
The steps below are exactly that checkpoint.
|
Step |
Action |
What You Are Looking For |
|
1 |
Check terminals at battery and solenoid |
Clean contacts, no visible corrosion |
|
2 |
Key on, press accelerator, listen carefully |
Pinpoint front or rear, electrical vs. mechanical |
|
3 |
Test solenoid input voltage with multimeter |
Should read close to 72V |
|
4 |
Test solenoid output when pedal is pressed |
Input match = solenoid OK; zero output = replace |
|
5 |
Raise vehicle, rotate wheels by hand |
Grinding or resistance points to bearing or CV issue |
|
6 |
Inspect four-pin accelerator connector |
Pins fully seated, no pushed-back or loose pins |
Once these steps are complete, the fault direction should be clear. An electrical finding points to the relay, solenoid, or wiring. A mechanical finding points to the axle or bearing. If both systems pass, the motor controller wiring is the next area to check.
For symptoms that shift from a click toward a grinding noise, the tracker ev motor grinding noise guide covers what that progression signals and which component to prioritize.
Is It Safe to Keep Driving a Clicking Tracker EV?
The answer depends entirely on which click pattern you have confirmed.
If the noise is paired with any loss of drive, a voltage gauge drop, or an unusual steering response, stop the vehicle and run through the diagnostic steps before the next ride.

Click Type |
Safe to Drive? |
Recommended Action |
|
Single electrical click, normal power otherwise |
With caution |
Schedule inspection within a few days |
|
Repetitive click with intermittent hesitation |
Limit use |
Diagnose promptly |
|
Mechanical rhythmic click that is worsening |
No |
Stop and repair before next use |
Here is a clearer breakdown by risk level:
-
Drive with caution:
A single click at pedal press, with normal power delivery after. Low immediate risk. Get it inspected within a few days.
-
Reduce use:
Repetitive or worsening clicks, particularly with hesitation or partial power loss. The fault is active and can escalate.
-
Stop:
Rhythmic mechanical clicking that is getting worse, especially when paired with vibration, steering pull, or a grinding undertone.
A failing CV axle can cause complete loss of vehicle control at joint failure, which carries real consequences on the remote terrain where the Tracker EV is regularly used.
Electric UTVs carry a 40 to 60 percent maintenance advantage over comparable gas-powered models under normal operating conditions. A click addressed early keeps that advantage intact.
If the mechanical symptoms shift beyond a click, the tracker ev clunking noise from front end guide covers that next stage of drivetrain behavior.

Frequently Asked Questions
What causes a clicking sound when accelerating on a Tracker EV?
The most common causes are a failing contactor relay, a worn solenoid, a damaged CV axle, or a loose connector in the accelerator circuit. The pattern of the click, specifically when it occurs and whether it is rhythmic or tied to pedal input, is the most reliable way to narrow it down.
Is it safe to drive my Tracker EV if it is clicking?
It depends on the type of click. A single electrical click from the relay or solenoid at startup carries lower immediate risk. Rhythmic mechanical clicking that worsens across rides is a different situation, especially before any off-road or remote use.
What is the difference between the solenoid and the contactor relay on the Tracker EV?
The solenoid is the main high-current switch that routes battery power to the motor. The contactor relay is a smaller component that sends the activation signal to trigger the solenoid. Both produce clicking when they fail, but at different points in the acceleration sequence.
How do I know if the click is from the drivetrain or the electrical system?
Electrical clicking is triggered by pedal input and occurs at the same moment every time. Mechanical clicking is rhythmic and tied to wheel rotation speed. It changes as the vehicle speeds up or slows down, and it shifts during turns or on uneven terrain.
Can I fix a clicking Tracker EV myself without going to a shop?
In most cases, contactor relay replacement, solenoid work, and CV axle repairs are all feasible for an intermediate DIY owner with basic tools. A loose connector check takes nothing more than a visual inspection and a screwdriver. Confirming the right fault before ordering any parts is the step that matters most.
