Seven up Williams, was working fine a couple weeks ago.
So my ball count stepper unit which moves from ball ball 1 through five seems to have an issue. I have taken apart and thoroughly cleaned and lubed as suggested however it still won't go from ball one to ball two. I can manually step it without issue.
From ball one to two is slightly more work for the stepper as there is an extra bit to push past. I can see the coil activating but it just doesn't seem to have the umph to get it past ball one.
I really thought the full clean and lube would do it, what's next? Could the coil be under powered or not functioning properly? Something with the outhole or ball index relays?
