i tried jims coin optic test on a game im having trouble with, wont accept a coin. the comparator rake doesnt pull in, and shimming the rake to direct coins into the optics doesnt help. they go thru, but no credits. . in the test, i get no response in 10_1. it stays on 1 . test 11_1 and 12-_1 work fine, toggling 1-0 . this is with a brand new optic unit. i did notice the coin guide is marked 5 cents. i'll post a pic with a quarter in it. the game had quarters in in when i got it, and the guy said he was using quarters. looking at the guide with a quarter in it, it looks like it should work, but am i wrong and the 25 cent guide will solve this? i get no coin errors, and it takes bills.
i read other posts about removing Q4 on the optic board. i did that on the orig board, and got an immediate code 21. that would be expected i guess, no q4 would make it think it was blocked. well, i tried
. i'll replace Q4. i post the pic in a reply, it seems to choke when i attach a pic, even though i shrunk it to 224k
thanks much
