on Wednesday the rebuilt alternator comes in just what i needed a VALEO with the 8 ribs .... unpack it gettin ready to in stall and the damm thing will NOT SPIN at all so now have to ship back and get another one...thats right i have bought 2 so far and had to send both back.. this is one of the down falls of buying on line and buying a rebuilt alternator, I'm thinking i should have had mine rebuilt i would have been done by now.......
