battery light on and off

Maybe just try for a used one at the salvage yard and swap the chip over.

Looks like a bear. I cannot see the bottom bolts, no room.
Also there is one plastic connector I cannot figure out how to remove it.
I read here some where that Bosch is not as good a Denso, I can get Bosch but not
Denso, locally.
Any truth about Bosch?
Thanks
Steve,

The belt tension is 5 mm of deflection at the long stretch. With the alternators, you want to stay away from anything other than the OEM one, as none of the aftermarket ones seem to properly drive the charge warning circuit. OEM junkyard or ebay ones are the way to go. If you go for one off an 09 you can be absolutely sure that it has the newer regulator.

I found a used one from a 2012 sedan. It's cheap enough.
But will it swap out? I can't see any reason just to swap modules.
Unless I can do it in place without removing the alternator.
Is there a DIY on this some where?
You guys are great.

Should just swap right in.

It will just swap in. For doing the swap you just need a 12mm wrench for the top bolt and a 14mm for the bottom. The bottom one can be tough to get out, so if it doesn't feel like it is going to loosen easily, hit it with some penetrating oil before trying too hard. The threads are on the right side (as you are facing the engine from the bumper) so you want to hit that end specifically.

For replacing the regulator itself, here is what is involved:
