Hi all, interesting problem has cropped up, when putting my wisper 905se on charge, the amber light switches straight to green and the fan cuts out, subsequently, I cannot charge up the battery, I have (with damaging the holder) changed the top battery fuse, and checked the fuse on the charger, apart from that I'm lost,the battery is only about 18 months to 2 years old. Anyone had similar or the same problem occur? I would as always be very grateful for any responses. Thank you
