I have just purchased a spiker the biker machine by barcrest for my son, when all the doors are on it alarms and says ''tamper pnd opto blocked alarm 17-83'' I would be very gratefull for any help or advice?? :
Please excuse my ignorance but what is the mech? I have stripped down the coin hopper and removed the controller with the pecentage key on and replaced but to no avail. :
Try Stripping down the Hopper again. This time take particular care to clean the little glass opto. This is the light (EYE) that counts the coins as they leave the Hopper. There maybe a hair or a little dirt on it or the reflection part nearby. Goodluck
