Bally Night Club Bingo Machine Restoration Part 2: Getting it Running!

In part 2 of the 1956 Bally Night Club bingo pinball machine restoration series, we install a new mixer motor in order to get the machine to power itself on without blowing fuses, figure out what other problems the machine has, and do a lot more work on the mechanical side of things with the help of the original pictorial diagrams, switch charts, and the machine schematic.

Thank you for taking your audience through the prcess, great video!

The spotting disk should turn ONLY when the machine is in the spin cycle ( only few seconds ).
Now for the ball, did you have all the eight balls in the trough because one less and no balls will go to the playfield , because in early machines players were cheating so they wired later machine to act this way.
Thanks for the upload.

@@arnbon6241 Yes, I eventually figured out that the spotting disc and ball motor should run only in those situations. All 8 balls were present, and towards the end of the video I figure out that a switch in the ball trough needed adjustment so that the balls would load.

MAX, when looking at various pinball games schematics the fast & low blow fuses are often go to different circuits and voltages but what determines a circuit to either use fast blow or slow blow?

[@MaxsGarage]

It depends on the circuit. If there's a short circuit, the fuse should blow immediately (fast blow). If it's a circuit that normally draws an amount of current close to the limit of what the fuse can handle, it needs to be a slow blow fuse so that the high current draw doesn't blow the fuse when it's not supposed to.

@@MaxsGarage I'm still confused how to tell or what determines a circuit to use a Slow Blow Fuse? example if the circuit is drawing pulling 500mA you will use a 550mA or 600mA slow blow fuse but most slow blow fuses have a T for timing I think in uS microseconds. So I don't know the uS microseconds timing of the slow blow fuse based on the circuits current draw/pulling?
