my up and down ramp doesn't go up in time and ball gets stuck under ramp, I tested coils and both read 11ohms, cleaned coil sleeve, replaced 3 220ohm resistors that looked burnt and leaky 100uf capacitor, soldered cracks joints on ramp board and grease ramp joints but still ball gets stuck. Might be bad ic on ramp board under playfield or wiring issue. What do you think? I do notice if I hold flipper button while ramp is switch is triggered then ramp doesn't go all the way up in time but if I toss the ball by hand to right freeway loop the ramp goes up everytime and ball passes. Weird. I check all the threads no one had that issue. Please only answer if you have a possible solution to prevent mass confusion. Thanks

Good awswer but Yes, I ran a test and when I threw the ball by hand the ramp goes up and ball passes but if I shoot with the flipper the ramp doesn't go all the way up in time and ball gets stuck under the ramp. It feels like power loss issue maybe loose wire or bad ic on board.

I tested the switches in settings but they seem good. I bought this Pinball machine few weeks ago, It was on location maybe it's the bracket? What's different about this bracket?

That's interesting, I thought that metal brace was factory. Thanks for the help I'll try that.
