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 ?

Any clues ?

Thanks Greg, When the rollovers are activated the EE relay energizes & points register ok,but the darn rollover lights wont go out - The 3 relays definitely do not energize. Manually activating 1B,2B & 3b relays A,B,C lights go out & the center A,B,C lights come on as they should - so all switches are working. Wouldn't think it would be the coils as none are energizing. I do have continuity from EE relay to 1B,2B & 3b relays.

Someone had fitted a Williams coil to 1B'A' & wired it up using flimsy electrical terminals -on removal of this coil to check it ,the wire broke off at the coil (refer pict) & will be impossible to re-attach so I have ordered a new coil. Hopefully this coil may be the problem.
Is this correct - if 1B'A' coil is not working properly, 2B'B' & 3B'C' wont energize?

EE Series Relay has a A-9740 (20ohms) coil fitted -in the process of trying to locate locally (aust) what is listed on the schematic A-9733 (2ohms). Pretty sure a A-9746 (2ohm) will do as well. Hopefully this will solve the problem.

Final update. I received a A-9746 coil, installed it, and have working rollovers!
