IGT S+ SP1271 & SS4479
I tried a new game chip which was not compatible, so changed back to original, cleared codes, but now bill validator not working.
Went through options and 6 (Denomonation) is set to ZERO.
Checked bill drawer, rechecked motherboard seating, hopper firmly in, doors closed and coin slot is accepting quarters, so machine functioning on quarters only.
I have searched and found nothing on how to change the denomination setting, the reset key does nothing to that option.
Out of ideas, any help is really appreciated.
Thanks,
Marc.
