Hi Roy,

The 6 rollovers are all on the same circuit and it looks pretty straightforward - I agree with chas10e as the only thing in between the roll over buttons (my badly drawn arrow) and the Bonus Step Up (which also scores 1000) is the Alt relay (yellow box). there will be a make/break switch where its either connecting my green direction (roll overs lit, bonus step up, 1000 points) or my orange direction which is 100 points.

So, you need to find the Alt relay, and find, clean and gap the switch that has a Blue with Red trace wire to one blade and a Brown with yellow trace wire to the other blade .

As for the 100,000 light, that should be easier - first check the bulb! Then the only switch that needs checking is on the relevant players 100,000 relay:

The wires going to the 1st player 100,000 switch in question is colored "98" (grey with black) and brown (not shown on this snippet)

Good luck!
