So not sure what happened here. I replaced the trap door assembly, since the old one had the stopper part on the bracket broke off, so the door was eating into the playfield. I put the new bracket on, and the coil seems like its lacking the power to open the door. There doesnt appear to be any extra resistance on the door, and the coil shows 72v, so it seems to have power. the sleeve is clean and aligned, and all the other parts are working properly. Any ideas what would cause a sudden loss of oomph?
