Battery light

I know of three Boxster fires caused by idler pulleys that seized and caused the serpentine belt to catch fire.

When I bought my 2004, she only had 25,000 miles on her. I replaced the serpentine belt at that time, and one of the idler pulleys had already started to fail.

Good luck.

Hmmm...
You’ve given me a lot to think about. So I have an 02 S with 34K miles. I now have the engine exposed top and front with the alternator laying on my tool bench, voltage regulator removed. I was thinking I would just attach the new regulator tomorrow and install, slip the belt over the pulley and see what happens. If the battery light returned I would then go the alternator route. If it stayed off, I would put all the covers back in place and take a nice weekend drive. Now I’m wondering if I should just bite the bullet and order the alternator, belt, and pulleys regardless, replace everything and have it all done???

Nah...

Just replace the regulator and go for a drive if it's fixed. No need to go down the rabbit hole, especially at only 34k, unless you have reason to believe something else is bad or failing. Maybe just plan on doing the idler pulleys sometime in the future.

No need to go down rabbit hole but as cheap insurance I'd definitely do belt while you're in there. At only 34k it's likely never been done and at the ripe old age of 16 it's legal to drive on it's own in all 50 states - LOL. Keep old for an emergency spare just in case behind your donut in the frunk. An extra ~ $25 well spent...

Good luck

I agree. Ordered the belt and will throw it on.
It’s cheap piece of mind...
