Centigrade 37
Gottlieb, 1977Just bought a centigrade 37 I knew it was not working. When I turn it on only the backbox lights up and the score motor is buzzing loud. I am walking thru http://www.pinrepair.com/em/index3.htm#check. The backbox says it it has 15 games but i am not sure how to add credits. The black wire is cut, What should it do? Also whats up with the bar and silver tape? More importantly what should I do?
IMG_20200714_220531 (resized).jpgThe disconnected coil in your picture is for the coin lockout mechanism. It makes sure the game returns coins to the player if they try to insert money when the game is turned off. A lot of home-use games disable this mechanism (by cutting the wire) because the plate can buzz loudly when the game is turned on.
The broken bar is part of the coin lockout mechanism. It looks like somebody tried to tape it back together. You don’t really need to concern yourself with the coin lockout. It does not interfere with starting the game or playing it.
Here’s a good tip for you: whenever you see a black cloth-insulated wire on a coil, that’s the return path to neutral. The non-black wires on coils are color-coded so you can find them on the schematic.
15 is the maximum number of credits you can put on Centigrade 37. You can’t add more credits until the replay unit decrements one of those credits.
What happens when you push the red button on the coin door?
EMsInKC you were right the schematic say second chute not choice. This looked suspicious so I put some paper to block the contact and the relay stopped buzzing. I tried to add credits on both shoots. The second shoot did nothing due to the blocked contacts but when adding credits to the 1st shoot it set off the buzzing to the relay.
I think the short in the pic is coming from the the broken rod in my first pic which adds tension to the arm.
IMG_20200715_110511 (resized).jpgstuck coin switches account for a bunch of issues. now with those fixed nothing happens with credit button? if that is the case. then possibly contact on credit wheel not closed/dirty. the one that opens a zero. you can also activate tbe start relay by ha d and see if that starts it up
Red button is not working. Not sure what I am looking for on credit wheel. When I bump the start relay the score reel spins and the roll over assembly moves but nothing starts. the start relay buzzes very loud until you turn the game off.
I moved the top plunger on the credit reel which caused the games to go down if I turn it on after I do this the score reel spins but I get nothing after that.

On the credit wheel there are two switches. One for maximum credits that opens at usually 15 (it is adjustible) to stop the game from adding more credits, and a zero position switch that opens when there are no credits left on the game and opens the circuit to the start button.
Based on your posts about the score reels you have a lot more issues than just the start button not working.
Quoted from xddanx:emsinkc different game
We're not talking about C37 now?
Now when I bump the start relay it spins the score motor once and the hold relay stays locked. It does not stay locked in if i move the jones plug on the tilt adjustment to off. Which i think is normal?
Possibly unrelated or not important, whenever I turn it on the tilt and game over are flashing.

tilt and GO normal for power up. otherwise it would pickup where the game left off

That behavior for the hold relay is normal. Putting tilt to off with the jones plug makes the hold relay drop out when the game tilts. This is the most punitive setting for this game. When set otherwise, the hold relay remains engaged so you can continue a game.
Like pinhead52 said, it’s also normal for Tilt and Game Over to be lit on the backglass when you turn on the game.
