Hey guys my S2000 sound like it has a drill under the hood! I replaced the battery last week and now more fun this week. Anyway, is anyone aware of a walk through on replacing an alternator? The belt tensioner is my main concern because I can't seem to find it?

 

How do you know the alternator is bad? Was the battery replacement because it was losing its charge?

 

Throw it on the meter before you replace it.

 

I thinks its charging ok but not 100%, the bearing are making a lot of noise and my cluster gets dim and then they get brighter.
