The owner of a 2010 Jeep Wrangler brought it to the dealership because the battery was not charging. The alternator had been replaced twice in the past year and a half. The dealer found that the problem was not with the alternator, but with the wiring harness.
The wires had become frayed and were not making good contact.
If you have a 2010 Jeep Wrangler, you may have noticed that your alternator isn’t charging. This can be a problem, as it means your battery will eventually die. There are a few things that could be causing this issue.
First, check to see if the alternator belt is loose. If it is, tighten it up. If that doesn’t work, then you may need to replace the alternator itself.
2010 Jeep Wrangler Alternator Fuse Location
Assuming you are talking about the fuse for the alternator on a 2010 Jeep Wrangler, it is located in the engine bay. The fuse box is usually located near the battery, so check there first. If you can’t find it, consult your owner’s manual or a service manual for your specific model of Jeep Wrangler.
What Would Cause an Alternator to Not Charge?
An alternator is responsible for charging the battery in a vehicle while the engine is running. If an alternator is not working properly, it will not be able to charge the battery, and the vehicle will eventually lose power and stall. There are a few things that can cause an alternator to stop working correctly.
One possibility is that the drive belt that turns the alternator pulley may have come off or broken. This would prevent the alternator from spinning and generating electricity. Another possibility is that a fuse has blown or there is a break in one of the wires leading to or from the alternator.
This would also prevent electrical current from flowing to or from the Alternator. If your vehicle begins to lose power while you are driving, it is important to pull over safely and turn off the engine. Once the engine is turned off, you should check to see if any of these issues are present so that they can be fixed before restarting your vehicle.
Can Blown Fuse Cause Alternator to Not Charge the Battery?
No, a blown fuse will not cause an alternator to not charge a battery. The alternator is what charges the battery while the engine is running and it is powered by the serpentine belt. If there was an issue with the alternator itself, then it would likely be due to a bad diode or voltage regulator which could prevent it from charging the battery.
However, these components are not affected by the fuse.
How Do You Check an Alternator on a 2010 Jeep Wrangler?
Assuming you would like a step-by-step guide on how to check an alternator on a 2010 Jeep Wrangler: 1. Park your Jeep Wrangler in a safe and level area. Turn the engine off and pop the hood.
2. Disconnect the negative battery cable from the terminal using a socket wrench. This will prevent any electrical shorts while you’re working on the Jeep. 3. Loosen the bolt that secures the alternator’s positive battery cable to the terminal using a socket wrench, then remove the cable.
4. Unbolt the two (or three, depending on your model) bolts that hold the alternator in place with a socket wrench, then carefully remove it from the engine compartment taking care not to damage any of the surrounding wires or hoses. 5. Inspect your old alternator for any obvious signs of damage such as cracks, burns or missing parts; if it looks damaged beyond repair, replace it with a new one following Steps 6-9 below. Otherwise, proceed to Step 6 to have it tested at an auto parts store or by a professional mechanic before reinstalling it back in your Jeep Wrangler.
6. Bring your old alternator to an auto parts store or have a professional mechanic test its output using an electronic Alternator Test Bench (ATB). If it tests bad, replace it with a new one following Steps 7-9 below; if it tests good, skip ahead to Step 10 to reinstall it back into your Jeep Wrangler . . . but keep in mind that just because an ATB says an alternator is “good” doesn’t necessarily mean there isn’t some underlying issue causing premature failure so you may want to err on the side of caution and get a new one anyway (see Step 8 below).
Where is the Voltage Regulator on a 2010 Jeep Wrangler?
Assuming you are asking about the voltage regulator for the alternator: The voltage regulator on a 2010 Jeep Wrangler is located on the back of the alternator. To access it, you will need to remove the battery and disconnect the wires from the back of the alternator.
The voltage regulator is a small black box with two wire harnesses connected to it.

Conclusion
If your Jeep Wrangler’s alternator isn’t charging, there are a few things you can check to try and diagnose the problem. First, make sure that all of the connections are tight and clean. If they seem loose or dirty, try cleaning them with a wire brush or replacing them entirely.
Next, check the alternator itself for any signs of damage or wear. If it looks damaged, it may need to be replaced. Finally, if none of these solutions work, you may need to take your Jeep to a mechanic to have it checked out.
