so that 'a lot of rubbish you got!
forget the key, that's not original, for clocking up and try to start the queen by pushing the startrelay by hand.
The startrelay is on the back of the whiteboard, the second relay from the top
When yoy press the startrelay, the anti cheat relay, which is situated just under the startrelay, must get energized and must stay that way. That's important
Pressing the startrelay the control and mixer motor must start running and the playfield must open.
In opening the palyfield a lot of things happen.
The Tripbank will reset and so is the Tiltrelay and also all score and feature units.
If you really want a few points on the register, you can pull in the Replay Cam index, underneath the Control Unit and if everything is normal, the register will get you some credits
I presume you did already clean all Jones Plugs, cleaned the stepper units and inspected the leather clutches, so that everything is running well.
The Circus Queen is a nice machine, but if you don't understand what is happening it will/can you give a lot of problems and a headache!!
