Draining battery, brake and battery light turn on when I turn steering wheel

Battery light and brake light come on when I turn steering wheel. When driving lights flash on and off and when making a turn steering power goes out. I have had brakes both front and back replced. Timing belt replaced. Changed trans. Fluid. After the last thing listed it started with problems. Bat. Drain, replaced alt and battery. Turns on but when I turn steering wheel either way bat and brake lights go on and then off. Also the safety bag light comes on. Yesterday had to have it towed it died and wouldnt hold a charge. When I got it home the door locks and wipers kept going on and off without key. I disconnected battery. Put in new bttery and still flashing when turning steering. I only turn it on and dont try dri ing for fear of stallin and battery dying again.
