check theres close to battery voltage on ignition at the thin wire first as it won't charge without voltage there unless the engine revs are past 2500. other than that just disconnect the battery
EDIT: heres a link to the one i got http://www.hcdk.com/Default.aspx?ID=7&Gr...cing=VALEO or you could try a new voltage regulator as thats what goes on them 99% of the time which you can find on ebay with some cross referencing
