FWIW I think Im failing this test.
Coin Acceptor Test
The coin acceptor is active, indicated by the steady
amber LED on the COD board or the green LED on Coin
Mechanisms CC-16 acceptor.
An accepted coin will cause 09, Coin Credit, to
appear in the first two digits of the CREDIT display. A count
of accepted coins display in the right two digits of CREDIT.
A malfunction or improper coin travel will display
as 0A, Coin Error, in CREDIT. (See Input Ports Table).
I dont see a 09 or 0A output when dropping a coin in.
I dont get ANY feedback tbh. The green LED for the coin comparitor is on, but the yellow LED is off. Bad board? Dont know. I tried reseating the chip. I pulled the board, cleaned the IR LEDS, the prism, the block etc etc. I spent likterally 6 hours reading every post about the coin optic mechanism i could find on this board. mind you I have zero experience with SLot machine repair, just an electronics hobby background.
And it all DID work at one time, then the PSU died, i left it dead for like 5 years, then got a new PSU, put it in, everything seems great, but no dice on the coin mechanism.
Since Im not getting ANY error codes does that imply the coin comparitor itself is bad too? Shouldnt it see a coin pass, then when the optics dont pick it up, shouldnt I get an error about that?
