Hello. Just need some help. My 09 xB's battery died last night. I bought a new battery and installed it after making sure that the old battery was bad.
This morning, my new battery died. I know that it's the alternator but, my warranty is over. Is there anything I could do?

Please and thank you. Any help will be appreciated.

replace it. thats about it, not much else you can do with a bad alternator

 

How do you know its the alternator? Have you had it tested?

 

You are quite lucky tbh.... our alternator is so easy to get to being right near the top of the engine and easy to remove... i say remove it on your own... take it to Autozone or Advanced and have them test it... if it is the alternator... swap it out....I mean you are outta warranty and an alternator especially ours is soo easy to do....save yourself from getting raped on labor and DIY bro!!!

 

I have a sub and a navi I'm putting in soon. Should I upgrade and get the gold high output alternator? I know it's the alternator because when the car us running and the battery is disconnected, the car shuts down. Can it be something else???

 

And I'm only on 39,000 miles. Should the alternator be dead by now?

 

It's possible. It really depends. I've been running a high output model for the past 3 years with no problems.

 

I just replaced the Alti on a 02 F-150 the guy also had just bought a new battery but his alternator was bad I told him to get the HO alt instead since he has lighting and tvs in it.... so yeah get the HO at least you will be ahead the curve..feel me!

from what I have read on the forums here and on scikotics these xb's are famous for having parts go only after 24k on it ...so I would not doubt it... imo

 

Well, where can I buy a good alternator? With my subs being installed and my LEDs and navi, I guess I'll go with a better alternator. I've never swapped an alternator out? How hard is it???

 

Dunno if there is a DIY up for this yet but if there is not and no one beats me to it I will get you all the info and tools needed to get it done... will also get you pics if I can.... (weather permitting)

**edit**

Hopefully someone can lead you towards the HO alternator... my parts guy does not have them....sorry

 

Thanks. Can't say how much I appreciate it. I need to get this done asap.

 

HO Alternator

only one i found still working on the rest

 

That's actually the one I purchased. They didn't know if it would fit or not, so I bought it and if it didn't fit I'd send it back. I had to get the NST pulley because the OEM xB pulley is smaller than the OEM tC's.

DC Power has great product, but to my understanding takes forever to get product from them. Mechman also makes very high quality product. Make sure your battery's at full charge before you install a high output alternator. Otherwise it will kill the alternator fairly quick.

Hopefully this helps. I'd also recommend performing the 'big 3'.

^^DC Power's.

 

How are you out of warranty? Doesn't Scion cover 5 years/60k on the engine/mechanical parts? Or is it because of your mods?

 

My warranty was 36,000 miles or 3 years. I now have almost 40,000 miles.

 

And I need fast shipping, I can't be without a car.

 

Maniac may be the way to go then.

 

Honestly, I don't trust mechanics. I know not all of them are thieves but, I rather buy one and learn how to install it myself.

 

Luckly we share the same engine as the TC (newer yrs) and this write up is on the pulley upgrade but it shows you how to remove the alt.... pictures and all...hope it helps!

Please make sure to disconnect the battery 1st... also since its the alt you wanna remove you can begin at step 7 on thru...good luck
