ballys s5500 83F code cant seem to reset

[Rkrscott]

I purchased a ballys s5500 machine it was not working but the lights worked. I bought it. When i got it home i realized it did not work.
through doing some research i saw it had a code 81 so i replaced the battery. after that i tried to do a hard reset by jumpering the j10 pins and holding the pseudo coin and reset buttons. I'm reading about ram clear chips i wondering if i need these or do i have another problem. the code that comes up after trying the hard reset says first ch p then 83f. Any help would be cool.

You need to do a "Full Clear"
You just did a "Partial Clear"

SafeRAMâ„¢ Clear Procedure
For a Complete, Full, or Partial SafeRAMâ„¢ Clear,
turn the machine power OFF. Set the jumper J10.
Complete - Press and hold the PSEUDO COIN and
TEST buttons, then switch power ON. When the message
CH C displays in WIN PAID, release the PSEUDO COIN and
TEST buttons. The CH C message is followed by CL C.
Full - Press and hold the PSEUDO COIN button, then
switch power ON. When the message CH F appears in
WIN PAID, release the PSEUDO COIN button. The CH F
message is followed by CL F.
Partial - Switch power ON. The message CH P
displays in WIN PAID. The CH P message is followed by
CL P.
If an error was detected during SafeRAMâ„¢ Clear
as designated by E C, E F, E P in WIN PAID, repeat the
operation.
Upon a successful SafeRAMâ„¢ Clear, the button and
tower lamps flash. Switch power OFF and replace the
J10 jumper.
 Replace MPU Assembly and switch machine
power ON. The machine will enter a Reel Calibration
procedure whereby the home position is recorded in
SafeRAMâ„¢. For tilt-free operation it is important that the
procedure completes without interruption

Check the buttons, We tell every one to push them as hard as you can and then push harder.
This is what is said on the 83F.

83F SafeRAM™ Format Error SafeRAM™ formatting has been lost due to bad RAM IC, a dead battery, or if ROM has changed. (A complete SafeRAM™ Clear is required.)

Ok, Thanks again
So i pushed very hard on the two buttons hard enough to almost break them.
same result.
I'm pretty sure the buttons are working.
here is why. When i push the test button the red light comes on and when i just push the pseudo coin button i noticed i get ch f to come up BUT right back to 83F

Is the battery in properly and is the battery voltage good?

[Neonkiss]

Is the battery voltage good?
Is the battery jumper on the MPU installed?
Some folks remove the battery jumper when storing the MPU since the Bally machine have a tendency to eat batteries.



 

Haaa, tkrozleski beat me to it by 54 seconds.....

[Rkrscott]

yes the battery voltage is 3.63
yes the jumper is on both pins.
Im wondering if the the main chips are bad.
take in to consideration. I have not seen this unit work yet.

Maybe try reseating the IC's and do a full clear afterwards. Battery connections to board are good?
