OK - mystery solved - it didn't occur ro me that the blue wire actually connects to the blue wire feeding uniselector 2's solenoid coil, hence its length. I had assumed that the wire needed to be connected to uniselector 1 as in the diagrams, but in this case, not so. Another one for the unusual var...

Having checked the 1st and 2nd versions of the manuals, it seems to me that the model I have has a rather different wiring design to those shown. Nothing seems to tally with the expected wiring connections - so maybe this is a variant that was made in the factory, or it has been modified somewhat (a...

Thanks, I did study it before, but will check again in case I missed anything.

A quick update - the blue wire COULD reach across to the left hand uniselector (when they are mounted to the back board of the case) - but where it connects to is still a mystery!

Hi coppinpr, Thanks for your suggestion - I did try connecting the wire to that tag, but it made no difference - that's why the solder looks so fresh. Also, the blue wire, when connected to that tag, is very much longer than the other linking blue wires, which makes me think it belongs somewhere in ...

aa.jpg After much cleaning and some re-soldering of bad joints, I now have the Roto-Pool machine working well - BUT, one thing has stopped me crossing the finishing line - a blue wire has broken off the right-hand uniselector, and I have absolutely no idea where it should connect to (see photo). Th...

Ah - interesting point, I will check it out - thanks.

I have a Roto-Pool in for repair (the 2D-4D-6D payout version), and have got it working again by re-soldering some bad joints, cleaning all the contacts and switches, replacing bulbs and cleaning the sockets, etc. It now works well, with one exception - the payouts are rather strange. I get payouts ...

Aha so that's what it's called - presumably because a bell rang when you won!

Thanks for that, it is much appreciated.

There is a Whittaker's machine called "Monte Carlo Rally" on which you bet on European destinations which light up during play - could it be a variation of this?
