i have put in a new mother board that i got from would wide gaming and a new back plain mother board am still getting this error coin in jam
i have swap ed one of my door i/o cards plus spare ones i still get this error i have closed the door 10 times still nothing

i was wondering if the coin comparator could be the culprit or the power supply those our the one i have not replayed yet

i have turned off the machine and i pulled out both door and cabinet cards and turned machine back on i still get no other errors except for no reels disconnected errors when i pull out cabinet card out

I believe a bad coin comparitor could cause a coin in jam. I would swap in another to see if it goes away.

Do you know if the rake on the coin comparitor is operating properly or might be bent at all? Is the sample coin installed correctly?
