Bally EM 5 line pay, quarter machine repair help please.

Some of the old timers here will tell Not to file or sand the points.
The points have silver plating on them and sanding or filling will remove the coating and expose the brass
underneath. The brass is softer and will pit quicker causing more problems.
The old timer method is denatured alcohol on a dollar bill pull though the points.

So I did some cleaning of the connections where the bar drops after the first coin is put in. I dont feel like the problem is here. On the second coin, it sounds like the issue is coming from the upper unit, specifically the line unit step up relay coil area. And when I removed the upper unit to check on it and pressed the plate that is supposed to lower to make more connections, that plate was very hot. 

Maybe I am wrong, I dont really understand the order of how things are supposed to go. See if i have it understood correctly... The first coin goes in and the bar drops to release the arm and to allow a signal from the second coin to go to the step up unit which in turn will do the same to open a circuit to another coil for the third coin and so on???

If this is correct, then it seems like the problem is after the first coin and before the second coin? Would it be normal for that plate to get so hot? It seems like maybe it is and thats why the brown look on the coil paper?

Chuck,
If you remove the 4 screws that hold your light panel onto the front of the top unit assembly, then you can carefully lay it down and watch what is happening up there.  Also, you can reach in with a pencil to physically close your odds step up relay to see how it affects the step up coil.
Try it you will be delighted that you can actually watch it all working...

Here's a simplified view of what happens.
1st coin in releases handle coil and when the handle paddle drops it changes one of the HR switches to close.
This closed switch now takes the 2nd coin in and pulses the odds step up relay, which makes the odds step up solenoid fire and steps the odds unit one step.
The 3rd coin in also pulses the odds step up relay which makes the odds step up solenoid fire once again, and the odds unit steps one more step.
The 4th coin in (does the same thing)
The 5th coin in does the same thing HOWEVER a N.O. switch on the odds unit disc OPENS, and that switch kills power to the coin lockout coil (door) which prevents you from putting any more coins in.
Now, when handle is pulled, that handle release switch (N.O.) goes back to open, and its normal position is to direct the voltage to the handle release coil. It is a two way switch.
So, basically once the handle release coil fires and the handle is released, there is no need to release the handle again, so extra coins in go to give you your odds step up instead.
You should find a schematic of it on your free downloaded  bally EM manual, which I am sure you have downloaded.  I think it's around page 18 or so.
Hope that helps.

I have just dropped the top payout panel and broken the glass!! Is there any resource where I can buy a new one???   

[rokgpsman]

Just to be clear, you are needing the upper glass, the one circled in yellow in your photo below?
