This is my issue car started out loosing its power slowly n need to boost it later now you need boost it to start it what I did do was test battery and its good nothing wrong with battery its discharged a little not much but what leads me to think that it's the annotator on car is gone or was on its way out and this is why we need to boost it now and why we loose power when you go put up the windows while she's started she looses all power in the vehicle like barely has enough juice it seems to put up window she wont even lock the doors on the car she wont even charge enough to restart while running for 40 mins in that time to restart on her own so Iam guessing its the alternator because I don’t see it being in anything else unless I’m missing something there’s nothing in the car that’s plugged in or running. There’s nothing that is on no lights no interior lights no nothing so there’s no given reason for anything to train the battery, no reason to allow the car to run more powered than she needs to so I’m still going with my gut feeling and going to go with its alternator. It’s not the starter I know that I’m not a mechanic. I worked on a lot of trucks and I did a lot of work on trucks. that’s where my experience leads from so I just want your knowledge and your input to elaborate on what you might know on what it could be and maybe you can tell me a little bit more.maybe Iam missing something important because your the professional Iam not that's why Iam here asking questions and I appreciate your support and time in advance if I don't get a response back before Christmas marry Christmas and happy new 🎆 years

 

Battery boost she stays running but when she stays going for so long she will not start again after shut off nothing on the dashboard no lights no indication of anything no engine lights nothing no ringing of seat belt no nothing dead car soon as You turn it off basically the car is turned off. She’s off for good unless you boosted it again. The car seems like it needs to juice, but I don’t know where the problem is. I’m stuck on this and I haven’t got other alternator yet I’m still looking into probably Doing that and then I am working on probably doing Doing situation Hopefully today if I can get it on, I don’t know if it’s the problem or not, but I’m hoping with any problems given that is the problem and that is the only problem with the car and with given to the fact that that is what I think it is That there’s no holding charge. That is the problem with the car alone with power situation, not holding to charge and keep in charge in the car thinking that that might be the issue overall. So if you have any other suggestions on what it might be, please recommend more and if you have any ideas, what you think that it could be cursed or any ghost or any anything that the car might have

 

Has the battery been load tested and how old is it?

 

Yes its been load tested and a new battery was put in as well and still same issue

 

When the vehicle is running you should check the voltage AT the battery. When I start mine it reads 14.3 volts and settles down to 13.6 after driving a while. I have a USB charger plugged into my cigarette lighter socket that displays voltage. What year is your Camry and how many miles?
You can check the voltage with a simple voltmeter.

 

So sad, I hop before Christmas your car will be working well.

 

If you have replaced the battery with a new one and are continuing to have charging/starting issues then you need to look at your alternator. Remove it and take it to a parts store that tests them, most parts stores do and will do it for free.
