Why My Jeep Wrangler Won’t Start But The Battery Is Good- Bad alternator
If your Jeep Wrangler won’t start but the battery is good, you might be looking at a faulty alternator. While it’s a very simple problem, it could also be the cause of a stalling engine. The alternator is what keeps the battery charged and runs your vehicle’s electrical systems.
If your alternator fails to supply enough current, your engine will stall or sputter. If you don’t want to spend a lot of money on a replacement, here are a few things you can try to prevent it from happening.
First, check your alternator voltage. You should see a voltage reading of at least 14 volts when the engine is just fired. If the voltage remains under 12 volts, then your alternator is most likely bad. The alternator should produce at least 13 volts when it’s just fired, so check your battery voltage with a multimeter. If the voltage is less than 14, it’s time to replace it.
Another problem that could be affecting your vehicle’s engine is a dead battery. Your Jeep Wrangler battery might be functioning properly, but the problem with the electrical connection can interrupt the current flow.
If the wiring isn’t tight enough, the lights in your Jeep Wrangler won’t work. Another common problem with your battery is corrosion. The acid in the battery reacts with the metal terminals, resulting in a reduced current flow. Corrosion also causes clicking noises and poor contact.
Why My Jeep Wrangler Won’t Start But The Battery Is Good – Bad ground strap
The reason your Jeep Wrangler won’t start could be because it has a bad ground strap. This small piece of metal runs from the rear of the cylinder head to the firewall of your vehicle. If it is corroded, it may be causing the car to not start. If this is the case, you should replace it. To do this, follow these simple steps:
If you notice a weak connection between the battery and the ground strap, it could be a bad ground strap. In such a case, it’s recommended to replace the ground strap. It can cost anywhere from $20 to $80 to replace.
The majority of the cost will go toward the ground strap, while the remaining amount will go to the labor. If you’re looking to save money, you can replace the ground strap yourself. Make sure you check the ground strap in a dry place, such as in the engine bay. Use a multimeter on 20volts Direct Current settings.
Whether your Jeep Wrangler won’t start or not depends on the cause. Some problems are easy to diagnose, while others require professional assistance. A broken ground strap will cause intermittent starting problems, and a bad battery could mean a big problem for your vehicle.
While a faulty battery is the most obvious issue, it doesn’t have to be. A faulty alternator can be very frustrating – the car’s engine won’t crank, and you’ll be late for work.
Why My Jeep Wrangler Won’t Start But The Battery Is Good – Oil leaks
Trying to repair an oil leak in your Jeep Wrangler is not a simple task. The engine compartment of a modern vehicle is very compact, and finding an oil leak is often difficult, if not impossible.

Why My Jeep Wrangler Won’t Start But The Battery Is Good – Improper wheel alignment
A misaligned wheel can affect your Jeep’s performance. This can make it difficult to steer, reduce fuel efficiency, and cause tire wobble. You may also notice uneven tire wear, which can make driving a challenge. The tires will also wear down quicker than usual, so you should get them balanced. Putting off wheel alignment will only end up costing you more in the long run.
To check if the wheel alignment is the culprit, use a volt meter. A healthy 12v battery should register 12.6 volts or more. If it doesn’t meet these criteria, a battery may not be providing sufficient current to crank the engine.
Check the wheel alignment of your Jeep Wrangler, as it may cause this issue. Alternatively, if you’re not able to find a problem with the wheel alignment, you can try the next step.
If the wheel alignment is the cause of your Jeep’s failure to start, the next maintenance item is the tie rod and ends. Make sure that they are in good condition and tightened to the manufacturer’s specifications.
Improper wheel alignment can lead to death wobble, which is a sign of a misaligned wheel. Incorrect wheel alignment can result in a shaky steering wheel, bump steer, and excessive tire wear.
Unbalanced tires
A faulty battery may be the cause of the problem. However, it might be possible to get a replacement battery. A Jeep Wrangler won’t start when its tires are unbalanced. If you’ve had the battery replaced in the past, it might be time to replace it with a new one.
A fresh set of wheels and tires will give your vehicle a fresh look and feel. Moreover, new tires will boost your vehicle’s performance by providing better grip and ground clearance.
Next, you should check the tie rod and its ends. You can do this by using a jack to check if there’s movement in the tie rod. If it’s bent, it will cause wobbles and shaky steering. Also, if the tie rod is bent, it can cause excessive tire wear and increase the chances of death wobble.
A Jeep Wrangler that vibrates at high speeds is an indication of unbalanced wheels. It can also be a sign of damaged tire belts or a worn-out steering column. If you suspect this issue, you should get your vehicle inspected by a mechanic. Balancing wheels might not solve the problem, so you need to replace the entire suspension system and tire belt.
