                                            LIN doesn't work

                                            Nicholas

                                            in a year

                                            Had to disconnect the LIN wire as this alternator doesn't communicate properly with the vehicle computers. Connecting the wire will even cause the battery regulator to stop responding as they're all interconnected. It operates and charges the battery (slowly) without the LIN, but without it connected the car cannot control the alternator's output. The old alternator's pulley went bad and was slipping, but the LIN still worked, so I know my wiring is good. Will be returning this once my OEM alternator arrives.
