Ball in play and Player up lamps not working:
-->>
So I have had this game for a while and just started to attempt to get it going over the weekend. Using my limited EM repair experience, I have it almost 100% working. The two items that do not currently work are the "player up" lamps and the "ball in play lamps" in the insert panel.

Yes, the lamps and sockets have been checked and they do work.

I feel the need to mention that there was some cut wiring in the lower cabinet that I have done my best to repair.

Again, the game is completing a 5 ball, 4 player game and everything else works properly.

I think I have traced the problem down to a Blue/Yellow wire that shares these two sets of lamps.
I do NOT have a schematic but I do have the manual on ipdb.org
When the game is going through it's start up sequence, I do see a VERY brief flicker of the #1 "ball in play" lamp.

Not certain what wire path to look at now. I do know that the fingers on the ball in play unit AND player up unit are making contact properly, as I cleaned those units/discs and checked their movement/continuity with my meter. Also looked for broken wires for a long while on those units and discovered none.

I cleaned the fingers AND discs on both units and made the common check of moving the fingers slightly and pressing firmly with no change. I'm leaning towards a wiring/switch issue because there is no voltage at those disc nipples/fingers.

I've also cleaned and inspected all the plugs in the head and cabinet for poor connections and have ruled that out as well.

Ah, very good. I will check that out this evening and report back.

Ok, yes, the game over relay was not adjusted properly and that was the issue with no lamps for ball in play or player up. Thank you CrazyLevi!

So now there is another small issue... now the ball in play and player up lamps are working... However, once any points are made on the playfield (no matter what ball it is) the “ball 3” lamp comes on(along with correct ball lamp) and 3 stays on until a drain, then game goes to next player and when that player scores first point, the “ball in play 3 lamp” stays on for the rest of that player’s ball. I suspect a wire or switch is wrong somewhere. ?

Yes, it’s not specific to a particular playfield switch or point value.

The only relay I see held on WHEN THIS HEPPENS is the “ball index” relay. It seems that a wire in that relay (5 switches) is crossed with something that it should not be. It’s this switch in the middle with the yellow wires / green(or grey?) wires, part of the Ball Index Relay. When I open it alone, the 3 lamp does go out. But I can’t just open it because the 3 lamp would then never come on.
Anyone have any ideas how to get it right again?

Thank you for the suggestions. I will check on the Extra Ball Relay switch and report back.

It's this one. I really can't tell:

It's part of the fun fixing an EM!

Ok, the first problem was that two wires were crossed. They were both tan/yellow. Once I fixed that, it got the ball 3 lamp not being on every point that is scored. The next problem was that ball in play lamp 5 was not working. That was resolved by tracking down two more crosses wires. They were grey/brown looking. Swapping those resolved that problem.

Like I previously said, a lot of cut wires looked exactly the same and it took some process of elimination to get the game working properly.

Now I’m down to one VERY small issue. The player 3 lamp in the lower right of the back glass is not working. This is really not critical to play a 4 player game. So I’m calling the game 99% and am going to start shopping it. Thanks to Sadacrack, CrazyLevi, and the other suggestions! Game is up.

Yeah man. I resolved the player 3 lamp now. It was this top arm on the coin unit not being clean.

-->Game Over lamps not working:

Found a new problem and updated the name of the thread. Game Over insert lamp(s) not working... Will post here if I can figure out why.

G.O. Relay is latched or unlatched, depending on if the game is in play or not...

There is an additional problem I have just discovered this evening though that is of a greater significance. —> The bonus unit adds up and counts down properly, as indicated by the inserts on the PF... however, at the end of a ball, no bonus points are ever awarded.

Ok, the game over lamps were not lighting because both bulbs were out. That’s was easy.

The bonus count up was two more crossed wires: these two looked exactly the same. (Red/GRN):

I think it’s all good now.
