The loose wires went to the coin lockout coil, which has been removed along with its hardware. It's function was to direct coins to the credit switches when powered up, or return coins when the game was turned off. Game will play without it.

The Hold relay locks in at start. The playfield jones plugs have to be connected to check game functions, with ball in outhole, credits on credit wheel, and score reels at zero.

Just as an FYI, when you separate wires that someone else has tied together, pay attention to the wire colors. If the wires are different colors, then it may be OK to separate them. If the wires are the same color, it's very likely that you don't want to separate them, even if doing that seems to fix a problem.

The electrical parts on the coin door, like the rest of the game, will often have "daisy-chain" wiring. A common wire that needs to be connected to several different components is run from solder lug to solder lug of each component, such as the coin switches, replay button, etc. The result of this is that you will often find two wires of the same color soldered to one lug of a switch or coil.

When people remove electrical parts such as the coin lockout coil, if there is a daisy-chain wire connected to one of the solder lugs, they must tie the two same-color wires together, otherwise all of the electrical parts downstream from the removed part will stop working.

So, if you separate two wires of the same color on the coin door, you're probably going to disable some of the electrical stuff on the door. This may cure a problem like a stuck coin switch (for example), but it may also create another problem (for example) like a non-working replay button.

adding my 2 cents here.
The wires on that door look tired.
chk out the slam switch the one with most of the coating burned away.
look over all those door wires, if something burned the coating off the end, it may have burned somewhere else along that wire.

If the two wires that you separated are grey wires, then you may have disconnected the anti-cheat switch on the front door when you separated those wires. With that anti-cheat switch disabled, the R relay will never energize.

The purpose of the R relay is to ensure that the game is forced to a game over state when it is first turned on. This happens because switches on the R relay cause the game over relay to trip if the R relay is in the non-energized state. This will always be the case when the game is first turned on.

The R relay is pulled in by a switch on the start relay. The R relay has its own lock-in switch that keeps it pulled in all of the time after that. During the normal operation of the machine during the entire time it is powered up, the R relay will never drop open - it stays energized 100% of the time. The only way to get the R relay to drop open while the game power is on is if the user picks up and drops the machine (causing the bounce switch on the bottom board to open briefly) or if the user pounds on the front door (causing the anti-cheat switch on the door to open briefly).

So, your first repair task is to get the R relay to stay pulled in by itself 100% of the time when you push it in by hand, or start a new game. It may be that the wiring you separated on the front door needs to be tied together to get power back on to the R relay. You may also have a burned-out R relay coil - this is a possibility because the R relay is on all the time, and it gets very hot in operation. To test the R relay coil, you can run a jumper wire from the 25 VAC fuse holder to the non-black wire solder lug of the R relay coil. If the coil is good, that will cause the R relay to pull in.

Once the R relay is working as it should, you can start to deal with the other repair issue(s) in your game.

OK - If you re-connect those two wires on the coin door, does the R relay stay in by itself when you push it in?

That's good progress!

Next thing to do is get the start relay to stop pulling in all the time. Check for a coin switch or replay button switch on the front door that is stuck closed all the time.
