A few weeks ago the pop bumper on the top level of the game was working fine but now it's really weak. It still fires but I noticed the metal ring didn't return to its place immediately. It moved slowly and I had to give it a helping hand. It probably means it's kicking down slowly too - which explains its weakness. I have a Pascal board and Pascal pop bumper boards so they should fine.
I'm about to strip it down and rebuild it but don't know if I need a new coil. Can you have a weak coil or does it either fully work or not work?
Thanks
Matt
