Have a Cross Town pin which appears to have a small issue.
The card says that lighting all bumpers (crossing to rollovers) lights top lanes occasionally for Special.
It would appear that the top rollover guides light up, one side at a time on a random basis depending on the 0-9 unit position.
You can score a replay for rolling over the top left or right rollover switch (one or the other but not both at the same time) but the rollover guide doesnt light. The wire from both the top left and right globe socket runs to the 0-9 unit and I have metered a circuit to that point and it is ok.
I have checked the 1-4 sequence complete relay switches and all looks good.
The 0-9 unit is clean and all wiring is intact.
Any ideas where else I should look or does anyone have a schematic?
And yes the globes are working as i of course jumpered power before looking any further.
Also it seems that the fan target "except special" light only ever lights when the numbers are paired and never randomly as it should.
Any ideas greatly appreciated.
