Hi,I have williams full house.i went to wax playfield.lifted playfield to look at relays.set playfield back down .now no power to playfield switches.pop bumpers do work when manually pushing in relays under playfield.just no power thru switches,please help.

Maybe but I did thorough cleaning .and everything else works correctly.played about 50 games.went to wax playfield .lifted board to check a relay under playfield.evrrything seemed ok.went to start game and no power to switches only.

Thank you Howard r for showing up.i will do.ill report back tommorrow. Again thank you for your help.

Again thanks.i will do.i will definitely report back tommorrow. I'm going to inspect the outhole relay ,as Rolf Martin suggest in another full house thread.then diagnose circuit as you suggest.again thanks and will update tommorrow.

Hi,Howard r.im making progress.did jumper test.once I did that ( connected jumper wire) to pop bumper switches.i had power to playfield.then i cleaned switches again on outhole relay and tilt relay.now I have power to playfield without jumper.problem now is ball kick out coil seems weak ,won't kick out ball to shooter lane,.coil barely fires.before problem I installed new coil and kick out switch.ball kicked out strong.if I manually kick ball to shooter lane .game will play. ( go thru ball 5 and game over.) I read a thread posted earlier ( full house ball eject)and followed Rolfs instructions,although I'm going to read again.found one problem on score motor switch.see pic.old wire broke clean off. ( bad connection).but tffer did not finish post to say how or if he corrected problem.im hoping we can solve problem and finish that post for the next poor soul.again thanks .I remember you saying in our last forum to diagnose problem and fix only that.any suggestions.

Hi,HowardR, yes sir .coil fires strong.will diagnose and report back on (full house ball eject) thread.Other pinsiders please see other thread also as I plan to report diagnosis and repair.Also I want to thank you Howard R for your help on diagnosing no play field power.i believe it was a combo of dirty and misgaped switches on the outhole, tilt relays and broken wire on 5th and 6th score motor switch stacks.I feel I'm learning proper ways to diagnose and repair problems.again thank you.
