I have been fixing a machine i have called wild thing running on an Impact mpu. I got it working except for one small problem. when it has to pay out, it gives an error 100p hopper jam. i changed the hopper and this was still the case so its not the hopper. I put the machine into test mode and tested the payout. When i try to payout a £1 coin, the hopper turns slightly. i have to push the collect button about 5-6 times for a coin to pay out. on the other hand, the 10p hopper pays out fine. It seems like there is a very low voltage going to the £1 hopper but I just don't know and not sure how to fix this.
Anyone come accross this before or know how i could fix it? Thanks.
