need help with coin jam eror

[staz]

ialso noticed a coiple of fuses on the right of the board.....how can i tell if there bad?

[Foster]

I doubt they are blown, I dont have an Enhanced motherboard schematic to be 100 positive so the next statements and is only a educated guess
I suspect that the most if not all I/O devices would be off and maybe even the MPU:
VFD, player display, Bill Validator, Printer, back lit reel controller, etc would be off if the fuses are blown.

[staz]

okay these 2 fuses are on the led board thar half the lighted amounts work..... im new with this electrical stuff do these fuses look bad?

[stayouttadabunker]

Those fuses appear to be okay.
To check them for sure, all you need is a basic multimeter.
You set the multimeter for continuity and touch each leg of the fuse with the leads
and you should get a full continuity reading on your meter if the fuse is good! 

That's what the guys are saying about checking the SMD LEDs - pretty muc the same way you check a regular bulb with a multimeter.

No, unfortunately those look good Staz. If it gets to be a real pain in the ass I may have some time in June that I could look at it if you can't find anyone closer and are willing to ship me the top box back plane and mpu.

[staz]

finally got it goin such a simple fix board got loose on back led panel.....i wanna thank evryone for the help you guys are great!!!!!!

Awesome machine staz!  Congrats!

now that the lights work i have another small issue.....im hereing buzzing sound out of both top speakers when the lights are on in the top box..... i guess from reading on here theres issues with noise and 501 boards....... would resisters take care of the problem?  and can someone make the harness with the resisters and connecters for the top speakers for me?i will gladly pay for it..... i cant even splice a wire without screwing it up lol

[stayouttadabunker]

You're may be getting possible interference & induction from a power line crossing into a speaker line.
Resistors is just a guess on what you may need.
Not all quiet the buzzing the same as others.
A lot of that depends on too many variables.
Some machines need more resistance to "dim" the buzzing sounds to an acceptable level -
some need less.

Remember, you've taken the machine out of it's naturally noisy environment into your bedroom.
A drop of water in your bathroom sink is loud now versus a mom&pop wedding band playing at Foxwoods...  
Believe me ...NO ONE complains about s2000 noisy speaker buzzes at the casino!

FYI when wires cross at close to 90 degrees crosstalk, noise or other interference is none to very minimal.
It is more likely created when they run parallel to each other.

Any piece of wire is an antenna at it resonant frequency, which is why Cat 4,5,6 cable is twisted so the frequency of any inferring signal has to be very high to be picked up by it.
Also Very High voltages increase the chance of being picked up, that is why no one wants to be near 100KV or higher power lines.

[staz]

okay so in simple english what should i look for wires crosing the speaker wires?  now heres the wierd part the buzzing stops when i open the cabnet and the top led money lights turn off then i close the door and as soon as the lights go back on buzzing resumes....also when i turn volume up or down buzzing stays the same level...... will resisters fix the problem?? bunker your the harness pro can you make me some speaker wires with resisters and connectors.......

[Yoeddy1]

Believe me ...NO ONE complains about s2000 noisy speaker buzzes at the casino!

I do!  I always pull techs aside and ask them why the hell haven't those boards been replaced with 504B's or for the love of God at least had resistors put on the speaker wires.

I know how the noise is getting into the speakers.
It is not from other wires being too close to the speakers or harness

 I think the noise is being introduced via the power wires going to the amp
A way to test this is to unplug the black plug at the Amp, play the game until you get the LED's to come on and see if you get the noise,
If you do it could be more complicated than just putting resisters in the harness.

[staz]

i will def try that tomm and report back!!!

[staz]

unplugged the amp and the noise stopped so i def need resisters......can anyone make me a set for my top speakers......

[Foster]

Actually I would recommend a 504B MPU

If that does not solve the problem then one of us on here can add some resistors to your harness.
you would be soundless until you got the harness back and installed it.
