I have just joined! Through a friend of a friend I have been given what I believe is a Rotomat Juwel (looking at your posts) to try to fix (owner says it belonged to my Granddad, he used to have 3 machines blah blah blah). I know absolutely nothing about fruit machines, but I do dabble with old clocks and cash registers!
The main fault seems to lie with the coin checking mechanism. From what I can see, there are two parts to this; one sprung lever of which the bottom you can depress to let the coin slide into the storage tube and the other is attached to the crank lever and I presume checks a coin is there and then determines if the mechanism should operate.
I also presume the relationship between these two levers has to be set up perfectly for the machine to operate correctly? I would be extremely grateful if somebody could explain how these levers are supposed to work, then I'll see if I can replicate this I can upload some photos tonight.
Thank you all very much for any assistance you can give me. I know the owner will be absolutely chuffed if I can get the machine working for her again.
