Verify better that player 1 score reel coil is actually working. When you manually advance it to non-zero when game is off, and then start a game, does it reset to zero too? Verify whether pl 1 10 pt score reel is locking up too, or ONLY the chime and 10 pt relay. Or pop coil(s) or relay(s) too.

What happens if you start a two player game and let first ball drain to go to player 2? Same exact locking up except pl 2 10 pt reel etc. lock on instead?

If you cannot find a stuck switch on top of the playfield - - with your bumpers all hooked up with your workaround, does each one fire and release when activated? If you still had a dead one it's possible its score switch happens to be stuck closed causing the lockup right off the bat, which wouldn't release because the pop solenoid plunger doesn't pull in and open the switch there to release the pop and 10 pf relays. Steered me there since the whole thing started with that fried pop coil from previous owner.

>>when i hit a 100 pt pop bumper you here the bell and relay pulls and won't let out causing it to loudly hum>>
Hmm 100 points too or is that a typo? Does that pop bumper fire and release, or does it stay on, or not fire... and the 100 pt relay is stuck as well?

On the suggestion of manually pulling in pl 1 10 point reel solenoid, you merely want to make sure the normally closed switch near the solenoid is opening. Don't know if you are activating it with game off, or when you are in the 'stuck' condition.

Is the 10 point reel humming too? If not, it could have gotten cooked and gone 'open' too when the pop bumper was stuck on and went open, since the 10 reel would have been stuck 'on' too. You'll need to test that 10 reel coil by activating it with jumper wires from another reel or other coil in the game, or check it with an ohmmeter while game is off. Does the 10 reel advance on game start if you first manually advance it to something other than zero?

Hmm so
1. the 10 reel does work when game is reset.
2. 10 point relay should fire the 10 pt score reel, but it isn't even though it is locked on.
3. Since 10 reel does not activate, 10 pt relay will remain locked because 10 score reel does not fire and open the 10 pt relay circuit thru it's EOS switch.
4. Only locks *after* you activate a 10 point switch so it apparently is not a stuck playfield score switch.

Are all the switches in the 10 pt relay clean and adjusted and ones that should close when it's activated are closing? No broken off/burnt switch blades/points in it? If the switch in that relay for the 10 point reel is not closing, what is happening is what would happen. Or perhaps a jones plug socket/pin is still dirty/not making contact or a wire there came loose while you were cleaning them.

Could be the player unit in the head, too. Once reset is complete and game has begun, if the switch in it that enables 10 point scoring to go to the player 1's 10 reel is not closing/dirty, then this lockup would happen. Start a two-player game and then see if 10 point score locks up for player 2 also. If it doesn't, that would tend to isolate the problem to player 1, such as the aforementioned player unit switch. Assuming the player unit is operating with player # lights and ball # advancing on backglass as they should.

So both 10 and 100 relays are locking, and for both players. (I assume the 10 and 100 relays are not locking simultaneously but you are just activating two different playfield switches.)

Check the Hold relay, one switch in there must be closed after starting a game or ALL the score reels will be disabled, but it would not affect the reels resetting. I'm going by a my set of 4-player schems for same-era Fast Draw but I believe same principle would apply for a two-player.

With a game started, Hold relay would/should be 'on' and closing that switch.

Can u take one more pic of the schematics - the next page up from that one above? Thanks

<<should i be checking the score reel?>>>
The reel units themselves do not appear to be the problem, they work fine in reset and you checked the end-of-stroke switches, which should be closed when reel is at rest, open when it is activated. And you can't get any of them to score. More like a circuit that is common to all of them as per scoring only, like the player unit or Hold relay.

There's a motor switch that would open to deactivate scoring when the motor was running, but yours is okay since otherwise your 10/100 score relays would never activate at all.

Here's how your 10 point reels would fire during scoring, slightly different than a 4 player but same idea. Not really seeing how any circuits on the coin door would affect this. If the slam switch on the door was flaking out or you pulled the coin door plug, the game would just go to game over. The only thing you haven't checked yet is the player unit switches, a stack in it would alternate up and down with each ball of each player to route scoring to the correct player reels. Could still be an open circuit at a jones plug where this circuit is going from the cabinet to the head, like the circuit from Hold relay in the cabinet to the rest of the circuit in the head, and you said problem did start after you cleaned them.

You could use a volt/ohmmeter to trace the wire colors noted on the schematics along that whole circuit path from Hold relay to the reel coils to find out where it is stopping before it gets to the reel(s).

So since you've done some things... are you are still basically at same point where the point relays are locking up? What do you mean by playfield is dead - everything, flippers, slingshots etc. except the kick holes? Are GI and feature lights on or off when it's dead?
