Require more history 1/condition of H10 battery B4 this problem (blown Charger Fuse) occurred 2/perhaps battery condition severly depleted creating high current draw upon initial charge attempt 3/not certain if an circuit protection fuse exists in H10 4/Chk charger wiring for shorts bare contacts etc.
