[Badss540]

I'm thinking GROUND but first let me say I restored the entire car along with new harness front to back, after getting the motor in and hooking up the battery I went thru a check with all the electrics and everything worked fine, lights, blinkers, brake lights, horn, radio, reverse lights. Started the car let it run, while running I turned the steering wheel to check the power steering ALL fine then shut it off. Tonight I went out to run it thru the gears, jacked it up pressed on the brake and that's when the blinker lights ( both left and right) came on, released the brake put the left and right blinker on and nothing. Could it be the turn indicator in the steering or a bad ground that just appeared?? The steering column is a new IDIDIT tilt. Any suggestions??? Thanks
