warning light problems too

i have a 90 xr7, when i hit the brakes a little to fast, the anti lock brake light flashes. when the car is turned off, key out of the ignition the emergency brake light stays on, when i start the car it turns off. Is this accumulator problem too? if i let the car sit for any more than 3 or 4 days the battery is drained from the light

Just a thought, but i think your ABS relay is stuck on the ON position, you might need to replace it, the ABS relay is located on the passenger side firewall....
