Some companies have bad designs. It's worth it to have one around. So would you say that when I had that mechanic work on my car, they could have tightened my belts too much and caused my alternator to go out? Depending on the condition of the battery, and how long the Battery Light has been on, the vehicle should be able to run for. Well like I said yesterday I was going to install the new alternator but I found out my original one one in my car is fine and its not broke. They will be able to determine if an is necessary, or if another issue needs to be addressed. Turns out, Toyota had a bad design on the wiring harness.
Nothing else is weird with my car, every electrical works, car starts fine. Informed the service center about the window and told me it's not covered under warranty so I would have to pay to have it checked. I need to understand why the alight is not on when the alternator is not charging? Some remanned alternators can be duds. Many of these stores will test your battery for free. Boosting or jump starting is similar to normal usage which isn't any harder on an alternator than a minimal charge load. Is it possible its dying? I drove it from Pembroke to Queensbury New York and back----13 hours. No data is shared unless you engage with this feature.
To perform the headlight test, start your car and turn on your headlights. Exhaust heat and oil leaks can also shorten the life of an alternator, so fix them as soon as possible. Many auto parts stores will test alternators, starters and batteries for free, though you will have to remove the alternator to have it tested at an auto parts store. I would think a whine would be bearings, rather than brushes. Knowing how the previous alternators failed can give a clue about the type of issue you are dealing with electrical, mechanical. Judging by most of your recent posts my semi-professional opinion is that you need a new car, lol. Oh no, not now I thought.
Some mechanics, though, say they typically see alternators last about 80,000 miles. I think it rare that windings would be issue unless manufactured incorrectly. Maven This supports the Maven widget and search functionality. But if your vehicle is equipped with a heated windshield, don't turn it on; this can make alternator voltage go over 100 V. Check this by measuring the voltage with a multi-meter at the battery with the car running; even with the engine reving over freeway speeds it should not go above 15 volts. This also gives the tech a chance to look at your work in general and is less expensive than having the shop do the complete install.
One of the most common failures is bearing failure. Any electrical things you can shut off will increase this time a little. If any mechanic messed that up I have to question how they dress themselves in the morning. Once the light turns off, you've found the problem connector or wire. Once you determine that your alternator is bad, you have several options.
It will help you identify wires, specific components, and possibly suggest some specific tests recommended by your manufacturer. If your old belt was old, it was worn out and stretched, meaning it had less tension than a brand new one did. Remember that with tapered roller bearings, excessive pre-load can mimic this same damage. If your battery is good, the alternator rate of charge will drop after recharging the battery upon firing up the engine. Start the engine and let it idle. In these cases, the oil damages the brushes, usually resulting in a very deep groove in at least one of the commutators for the rotor.
Is it my car's alternator problem? Before you decide you need to yank the alternator and replace it, make sure you check the serpentine belt. Something is feeding power to the circuit, possibly a bad ground. Everything around the alternator looks clean and functional. You see they way they work in a simple approach — when you rev the engine to 3k and let back off really quickly, usually the alternator will stay in tandem with the engine but in this design the one way bearing decouples and lets the alternator mass continue to spin until its revved and couples again or it slows from mechanical and electromagnetic counter force. During steps two and three while your car is running, if your alternator tests below 13.
