1995 Isuzu Rodeo Question no power to 4 fuses

My wife was driving down the road when, the battery, brake lights came on and the blower motor stoped. I checked the fuses "with the key on"and discovered no power to the fuses.I then took the back off the fuse box and determined the relayes where not "CLICKING"on. I then put power to the out to fuse pin on the relay with my power probe and the blower motor turned on. The four circuts are heater, a/t lock/ac and charge, and they all have a thin solid black wires with gray spots to each relay. Do I have a bad b.C.M. Or what? I guess I need to find out where those black wires go to. Do you know? Please help, its been 2 days in my garage not woorking, also obveousley the alt is not charging the battery. Thanks for your time.
