I think it is time for a new alternator on the LS. I have a 2000 V8 sport. The battery light keeps coming on so I had the battery checked, and it is fine. My question is how hard is it to change the alternator? (The egine bay is so cramped!) Is a 110 amp ok if it is refurbished? I have seen alot of refurbished ones on sale online for under $100 with warranties. Also alot on ebay that are used but have lifetime warranties. Thanks
