Ford Galaxy multiple electrical faults

Same issue as below, previously reported by someone else:

Hi, My 53 plate ford galaxy has developed yet another electrical snag. The indicators have stopped working, but work when they are on hazards. The fans have stopped working as well. On the dash the ABS light is on and the brake warning light is flashing. Also when braking the fuel gauge drops to empty, bleeps and re-fuel sign comes on. I had a similar problem last month when all electrics failed. I ended up changing the lead from the alternator to the fuse box and the fuse box and this seemed to have got rid of the problem until today. I have also just recently replaced the battery. Hope somebody can give me any ideas as to whats up now!!
