Hi All.
I don't do any of my own work on my Yaris.
But my Battery light just came on and then it goes off and on every once in awhile.
I take it it's the battery right.
What kind of battery does the Yaris take.
I have a 2007 sedan.
Thanks much.

Search 'voltage regulator'.

I had that when the nut that holds the main cable onto the alternator came loose. It ended up welding the nut in place and allowing the cable to flop around (causing the flashing light). It also happened recently when the accessory belt was failing/exploding.

I ran with intermittent battery light for at least 2 years. It would only come on during or after days where the air contained high moisture content. Eventually it became a permanent light on situation and the alternator got replaced. I don't necessarily recommend or condone waiting. Just letting you know you probably have some time to deal with it.

It's also a pretty straightforward repair. Just a few bolts, one plug, and some careful leverage. Installation is the reverse of removal.

Thanks all.
It was on for the first minute or two this morning then went out. It rained heavily the night before. I will check battery and such today when back from work. If it's the voltage regulator i will have to wait for a few weeks till i get paid for a new alternator. I can get them for about 100-200 online or at napa. I called toyota dealer and they said it could be up to 800 dollars for them to replace it. I am really not good at carstuff. But my father is good at V8's and such. So we may be able to replace it.
Thanks all for your help. I really appreciate it. I put atleast 100 miles a day on my little Yaris and it has been a great car.
Thanks again.
