I picked up my second pin today - a Stern Lightning. I paid $100 for it and its in pretty good shape. The machine powers up and I can get it go through the diagnostics but every time I hit the right flipper the lights dims and I blow the coil fuse. I noticed the upper level right flipper is stuck - I cannot move it with my hand. Even when the machine is powered down. Do you think being locked up would cause that fuse to blow? I plan to rebuild that flipper and go from there. Do people recommend replacing/rebuilding both sides?
