o.k i have something else to say about the battery light lads, first thing is a standard 1600 cvh alternator can be 45amp or 55amp, the s1 r.s turbo has got a 55amp but the s2 has a 70amp alternator. if u have a 55amp yes it will charge but it will not give the charge [power] the battery needs. if you have a s2 make sure you have got a 70amp alternator on it. most peaple say any 1600 cvh alternator will fit but yea sure thay are right but thay dont think about what amp it is.
