V8 Freak

Can someone help me please... When I turned the engine off earlier and removed the key, the no charge (Battery symbol in dash) light came on. When I turn ignition on, oil pressure light comes on as normal but no charge light goes out. Battery appears to be charging ok and both lights go out when engine running. (As normal) Landy 110, 1989 V8 3.5 litre Any help or suggestions will be greatly appreciated. Neil
