Hi
Just a bit of background.....Have restored a number of purely mechanical machines, the only electrics in them were lights, my main hobby is jukeboxes, but every so often i restore a slot machine.
I have got hold of a Sega slot machine which is mechanical with some electrical parts which i haven't come across before my problem is that the solenoid which operates the lever so the arm can be pulled when a coin in inserted is noisy and buzzing loudly. To start with there's a transformer with 220 on primary side, with 110 volts on the secondary (for the flourescent lights) and 48 volts ac which is wired onto a half wave rectifier, 6 volts ac and 28 volts ac. The main area i am interested in is the 28 volts ac which powers the solenoid according to circuit diagram on the back. I have measured the voltage when the solenoid is operating and measures 19.5 volts ac, the resistance on it is 5,5 ohms, nothing marked on it indicating specification. I have cleaned the solenoid but no difference. Just wondering would the lack of voltage cause this, its unusual to get a voltage drop from a transformer or is it possible that the solenoid is faulty. Apart from that the machine is playing and paying out fine.
There are a few other components towards the back of the machine that i am not sure of, one is a rotary dial the the other a type of relay with a number dial on the side of it. May be related to jackpot payments but not sure. I will post some photos later of the various parts.
