well i just hooked up my vafc into my car, brown and black wires to ground (brown wire first) and then red and orange to power, well as i was hooking it up, before i got the second ground hooked up, the unit dial turned orange, so i continued with the install and the orange light shut off when i got all four power and ground wires hooked up, well now it wont turn on, ive tried pressing buttons, disconnecting it, its getting power because i checked continuity, anyone know?
