Coming along nicely now.. eliminated or identified most of if not all the problems!

Sling Shot and Knocker Coil fried

Number 4 Display Faulty

Credit / Ball Display bad connections

And Feature lighting fixed as above!

The Number 4 display does not show the 1 numeral in any of the segments, it is in the display as I have swapped it around and the problem appears in the same display each time.
Can this be fixed or am I looking for a new display??
