Title: Now I've Done It, looks like I broke it, can one of you incredable tech,s HELP!

 :131- :131- :131-  While trying to trouble shoot my games of Nevada coin mech something happened and now it only takes 1 of the 3 coins the others just fall out in to the coin tray you cam still flip the coin counter switch and get it to register all 3 coins if you open the door and flip the little wire thing, am attching a pic, can any one tell me what the H--l i did  :103-

Can you be more specific? What did you change or do, if anything? Are the coins being kicked out by the lockout tab engaging (the solenoid that magnetically moves the spring-loaded metal tab that is right in the middle of the coin path and that often buzzes) or are they just dropping through the mech (possible mechanical alignment/adjustment issue)?

All I did was pull out the coin mech to look behind it and put it back the first coin goes through fine when you insert the next coin it just falls through to the tray :103-

After a little more trouble shooting it looks like the the 2nd coin is being kicked out by the lockout, after you insert the first coin you can hear it rattling in the door if it stops rattling it will take the 2nd and 3rd coin, sporatic. can that be fixed or do you half to replace it?

I think there's a "Rake" behind the coin mech.
 The rattling sound might be coming from the rake's solenoid chattering.
A couple of things can cause this to happen.
1). There's insufficient power going to the solenoid due to a loose connection in the wiring there.
2). The rake is too far away from the magnet to fully grab the rake when needed.
You'll need to adjust the rake a little closer to the magnet for it to work better.
The only real adjustment is to bend the arm of the rake so it is closer to the magnet.
But it must be far enough away when it's de-energized so the coin falls past it.
Check the little thin wire that accounts for the coin switch also.
Make sure a coin actually pushes the coin wire to register a credit.
It could be bent a little outta da way and missing the other two coins as they go through.
The first coin might be kicking the wire and the other two coins miss the credit wire.
Finally, There needs to be a bit of coin separation in order for the credit wire to function right.
This is accomplished by a little bit of friction to separate the coins so they each hit the credit wire correctly.
 I hope this helps ya.
If not, get a new coin mech.

Sounds like your having problems with the scavenger coil behind the coin mech. That is the one that pulls in for the "rake"
My question to you is, When it worked before what would happen if you put in a forth coin?
Would it return to the front tray? Or did it take the coin and deposit it into the hopper without giving you a credit?
If it use to return the forth coin then you did do something with the power to that coil.
If it use to just take the forth coin and not return it, then it was probably broke before. Someone may have just had the "rake" held back by a piece of paper. When you removed the coin mech it probably fell out so now it's rejecting the second coin.

If it's rattling and then settles down, but is energized when it settles down, then you might want to lighten the tension on the little spring that pulls the plate away from the solenoid when it's not energized. The spring stretches between a tab at the end of the moving lockout plate to one on the coin mech frame. Be careful not to wreck the spring, though. I would also suggest cleaning the magnetic contact part (metal ring) of the solenoid and the back part of the lockout plate with some alcohol on a QTip. Also try jiggling the position of the lockout plate. It pivots through a large "tab"in the frame, and can often be quieted down by reseating it slightly.

If it's rattling and then settles down de-energized, then check the wiring to the coil for a loose connection or cold solder joint, and then work back, checking the wires for intermittent opens (internally broken wire), and then the solder connections at the other end, etc. It wouldn't hurt to check the continuity of the coil itself while your at it.

I just cleaned the the scavender coil and the plate gave the spring a little pull now there is no chatter , contunity is good, and when on it reads 51.5 vac to it, when you drop the first coin the coil releases the plate, is it supose to go back to the coil for the next coin or stay open? it stays open almost no power to it,the next coin falls to the tray, traced the wiring back don't see any cold soders or broken wires as a mater of fact the coninuity is good on both wires back to the baluee plug, not shure where it goes from there, I have a used Imonex - 25 cent acceptor, comming from foxsslots (ordered to change over to tokens) What now?
Thank you all, Bob

At this point I'm going to hand this off to Neonkiss, or one of our other experts, since I don't know the inner workings of Games of Nevada machines.  :131-

Your words "almost no power" are a clue. So there is some power, but too weak to hold the armature in? There will be a step-up unit to count the coins, a square brown board with rows of brass studs and springy wipers on a shaft that turns one click for each coin. One of the rows of studs controls the scavenger coil, so that it drops out when max coins are inserted. The step-up unit resets when the first coin is inserted, if the last game was more than one. There's also a bypass relay that pulls in so you can insert the first coin while the step-up unit is at max coins after a game. My guess is the springy wiper on the step-up unit is weak and not making good contact, so that after it steps once and the bypass relay drops out there isn't good continuity to the coil.

I  agree with Op-Bell on this one.
I believe your problem is in the step up unit it the top box.

I would also have to say that this was an issue with your machine before you purchased it.
It was not uncommon for someone to place a piece of paper behind the coin mech to hold that fork on the scavenger coil closed.
This would allow all three coins to register. However it also allowed any additional coins to be entered. They would be go directly to the hopper with no credits applied.

The purpose of that scavenger coil is when pulled in, it allows the coin to pass normally through you coin path of the coin mech and hit the wire of the coin switch to add a credit.
Once the machine has accepted the maximum number of coins (three for your machine) power to the coil is lost and that "fork" moves forward (via the spring attached)  That fork has a 90 degree bend in it. That bend sticks into the coin mech. It blocks any other coins entered from that point and sends them to the coin reject path of the coin mech. They then would be returned to the coin tray on the front of the machine.

You said your machine works good and counts all three credits if you manually flick the coin wire on the switch.
If you need addition photos let me know. My Games of Nevada machines are buried in my garage, but I need to clean it out this weekend.

Thank You All, I will pull that unit out and clean the contacts and see if that dose it, I got an imonex coin except-er to switch that machine to tokens, I pit it in and it works better than it did but still drops 20% or so of the coins inserted out the coin return,
Could that be the fix to an earlier problem I posted about reels 2 & 3 contuning to spin the power drops off to the clock timer motor causing the clock motor to stop before it had moved far enough to stop all 3 reels?
Neonkiss, dose that mean you have some games of Nevada spare parts or maby a manual for that games of Nevada machine laying around?  :131- :3- :131-
Thank you again
