I had the lower playfield upkicker coil burn up on my BH. I replaced the coil, but it remained unresponsive. I then moved on to the playfield mounted transistor that controls the coil. Upon replacing it the coil is now back to remaining stuck on as soon as I turn on the power. Is this a sure indication that the transistor on the power driver board is bad or could it be something else?
