My car seems to be completely dead (no dash/radio/lights/ignition/key remote lock) but after testing with a battery charged apparently the battery is completely full. I've tested while connecting to both battery terminals and the further down the cables, cleaned the terminals and checked all fuses, and everything seems to be ok. Could this be some cabling problems down the circuit or could there any other explanation for it?
EDIT: It's a 2003 Honda Jazz. I tested with the battery charger, I am assuming it is impossible to get a false positive unless the battery is indeed charged. The fuses I just looked at them, but I doubt it's a fuse issue as nothing works, they would all need to be fried.
