I am trying to locate a wiring schematic for a Yamaha 48 Volt Golf Cart Battery Charger, model JW9-82107-03. I have 2 of these chargers that have blown the main 20amp fuse. Initial inspection indicates no obvious failed components. I have tested the surge protecting varistors and they check good. Replacement fuse blows as soon as unit is plugged in. I would appreciate any information on where I may find the schematic for this charger, or repair advice from anyone who has repaired this charger with the same issue. Thanks in advance!
