This isn’t the worst. And sorry I didn’t take a pic. But spent a while trying to figure out why a Top Score always started a two player game. Only to find out someone soldered a jumper wire in the main cabinet so it would do that on purpose. Why??????

The worst problems to troubleshoot, in my opinion, are those where someone has installed a jumper or rewired something thinking they're fixing a problem....only really they are creating a bigger problem!

I just dealt with that exact problem. They shorted the coin door lights to the lockdown bar release lever frying several things. The tried to rewire it and I had to get the manual out to undo and properly put it all back. I then replaced the blow fuse and it all worked again.

Hey, that's better than my pioneer. They bent all the leaves of the switches in tilt hold and tilt so it was impossible to tilt - insead of maybe just disconnecting the told bob?
So this is hopefully a good hack. Flipper link on 1950 Spot Bowler and found the hole on one end of the link was seriously oval and allowed too much slop. Don't know if the part is available or not. But was a Sunday morning and wanted a fix that day. However, with the rod attached to it, couldn't just replace it from parts on hand. So drilled the out of round hole to just bigger than the smallest washer on hand that fit over the tension pin. Filled the hole with 4 washers, drove in a replacement tension pin, works perfectly.
IMG_7969[1] (resized).JPGIMG_7970[1] (resized).JPGThis is a 2 fer. Apollo just picked up. Who needs to replace the cord to get a longer cord. Just tape 3 wire 3 prong cord to the 50 year old 2 wire 2 prong cord. Then have seen more than one machine with plates and rods added to go across a coin door. But to go across the back box cover? And they even very neatly cut slots into the back box door for the plates to fit through. The rod was long since gone. And the plates will be soon. But think I will polish the bolt heads and leave them in.

Back in EM days, if a game was in a dark corner, clever kids used a large screwdriver to pry the backbox cover open a little from one side, then turned the credit unit wheel to maximum with a bicycle spoke. We mounted a microswitch detecting open cover and a loud alarm inside the backbox. Also securing rods like that were used.

For me, as a kid I doubt playing for free would've been loads of fun for very long. Half the adventure was figuring out how I was going to come up with the dimes and quarters to play. Ask my mom for it, or sneak it outta her purse, etc.

How many others would check the coin return slots of all machines in arcades, in hopes of finding change to play a few games? My parents were cheap and didn't give me very much spending cash. So I did what I could to support my game playing habit. Inevitably, I'd find a few bucks to play with.

Or hoping there was a game in the joint that somebody had walked away from with some credits still on it... or not realizing they'd won a match. Especially if the knocker was busted.

I guess I am just too honest. Would have never thought of prying open a back box. Not to mention, sticking a bicycle spoke into a cabinet with live electricity? Kind of a Darwin test. But like others mentioned, always on the look out for coin return change or free credits. Also, most of my playing was at the local roller rink, where we had the 4 Square dialed in. Would run it up to 15 games, then sell them for a buck and a half. Wait till the kid lost them, then do it again. Bet the operator wondered why 4 Square wasn't a good earner. LOL

Not a hack, but similar to your comment: Somehow when I was a kid (meaning in the very early 70's), someone figured out if you put in 2 pennies and a nickel (I think that was the combination) in a 25 cent coin slot, we'd get a credit. Then when you hit the coin return, I'm pretty sure we'd get 1 penny and 1 nickel back. Went to the mall, tried it...and sure enough, it worked. Don't recall what brand of pin it was tho.

Jon Norris, the Gottlieb pinball designer, used a large magnet
to guide the ball wherever the good spots to get points are at.
He would rack up several specials and extra balls without damaging
the game.
Oh the ways to get free games as a kid...
Back in the day, one of the largest theme parks in the US used tokens for their games. The tokens were very similar to nickels. If you flicked a nickel quickly into the coin mech, it'd pass as a token.
A local bowling alley has a checkpoint that was missing the door on the coin return. A penny could be flicked up into the coin mech and it'd give you credits.
Of course, I never did any of the above! Ha. Kids will do much that we don't do as adults. For example, I bought a shower curtain rod at Home Depot last week and it rang up for 1 penny at the self checkout. I called over the attendant to make sure it was right (she called the manager, and they stuck to the 1 cent price).
I taught my oldest boy (7 years old) how to check coin return slots for abandoned change. He does that now anytime he sees a game. Funny part is, he rarely plays the machines at my house. Hoping that changes as he gets older. I guess Nintendo holds his interest better at this stage in his life.
Quoted from Jahkub:Also, look at that beefy spring. Haha
What's that on, a Hercules?!

We called it the seven cent trick. Jam the nickel in real hard . Gently drop a penny, and gently another. Each penny after that would fall into the coin box for a credit. Push the coin return and you got the nickel and first two pennies back- seven cents.
Someone here on Pinside said they were the one who designed a fix to the trick for the coin chute company. Forget who.
Quoted from codered9394:Just found this on a wpc power driver board.
He applied the same rule as for fuses:
- if the fuse blows, it is the fault of the fuse, it is necessary to put a larger one.
- if the resistance heats up and burns, it is the resistance's fault, I put a more powerful one.
The board had to be repaired before, because we can see a redone track on the right side. But not by the same person, because it was clean work. The second time, the board was "repaired" by a butcher.

Hey now, the upper flipper has one. Here's the thing that gets me...you'd think if it broke off it would still be jammed under something or in the trough. But if the game is still working and the rubber isn't somewhere in the game, someone must have taken the glass off, taken the broken rubbers out, not replaced them, and thought it was all good.

The Sunrise Mall in Massapequa had a few large "wishing well" fountains when I was a kid. One was above ground and the water was just over two feet deep. I'd roll my sleeve up all the way, wait for the security guard to pass out of sight, then scarf up as much change as possible from the bottom. Mostly pennies but I'd get the occasional nickel or dime, and quarters were like manna from heaven. The Time Out attendants wondered where I'd gotten the twenty five soaking wet pennies I'd give them.

Careful, EM guys will argue endlessly over how much alcohol and magic eraser is needed to get the swirl marks out of that machine.

I did not see any sign of broken flipper rubbers on that machine. They were missing on purpose....

Now that’s a HACK !
From the same T2 in above post. The game was displaying some strange behavior when ever the drop target was done? The game would start over (not reset). It would randomly add players. It would tilt. Found the problem see photos below....

It would be awesome if it was wired to the lamp driver board.

What is the voltage rating on that yellow diode?
Quoted from pins4u:Hey, at least he got the batteries off the board!
I was appreciative of that aspect.

My old T2 used to have a similar problem sometimes when the cannon fired and hit the standup targets. Was the weirdest thing. It would add players to the game if it was still ball 1. It wouldn't tilt after the 4th player was added though. I searched for months trying to track it down and couldn't find it. Ended up selling it as is and the new owner informed me that after a lengthy search he found a tiny ground short in the wiring.
Trying to figure out if the transformer in my Dolly was bad. Why bother removing the good one from Eight Ball! LOL
Thankfully figured it out and no harm done (did not have any boards hooked up in either machine, simply testing voltages on the rectifier). I had wired in the new line cord backwards

Clever... Williams 4 player games were the easiest due to the longer width doors, but they all were susceptible to this type of 'delinquency'. Our gang did that on occasion; Williams were the typical victims, namely Strat-o-flite, Dealers Choice, and Triple Action... we used a straightened hanger in lieue of a bicycle spoke. We never spun the wheel all the way around in case someone were to look at the credit wheel and know that we couldn't have earned so many games on skill alone.

Watching players at one of the local arcades and noticed a lot of commotion on one of the games a kid was messing with something in a paper bag on top of a GTB Play Ball glass... as I approached I noticed the ball underneath the bag was stuck on the home run switch, reeling off hundreds of points and runs, and winning a ton of free games. He wouldn't show me, but told me it was his father's work magnet. Before I had any sense, I thought that was a brilliant idea if money was tight and no one was around to view the cheat.
