Just about sorted out all the problems except this one.
The A,B,C Lane Rollover Lights wont turn off after activating,they do score points but stay illuminated. (refer Video).
The 3 Switch stacks 1B('A'),2B('B'),3B('C') at the Sequence Bank had been wired closed (refer Pict).Removing the wire from these switches has not made any difference.
Have checked and cleaned these switches but still cant get these rollover lights to turn off.
The only relays activating whilst activating the lane switches are the 50 point relay and the EE relay.(refer Video)
Have noticed the FG relay in the backbox does not seem to be operating -not sure if this is related.
Any clues ?
