Wiring Schematic Seeburg STD4

[youngs2019]

Hello!
I’m looking for help finding a wiring schematic for the STD4 jukebox and was hoping someone could point me in the right direction. The jukebox is showing at 110v, but doesn’t seem to have any power going anywhere else. Trying to find the wiring schematic to test the boards.
Any help would be greatly appreciated!

There are many schematics you will need if you attempt to repair your machine.

The best thing to do is obtain a service manual. It should contain all the schematics you may need.

You can buy one from a reputable source listed here:

Thank you very much!
I just took a peek and I’m thinking/hoping this is the one we need:
Seeburg Electrical Unit Parts, Schematic, Mechanical Operation and Parts Manual R-343

Yes, but I'd go the extra step and consider the combo package, R-359A.

We got the manuals, and looking at the one with the schematics in it, we are trying to figure out what the voltages should be for the power supply board. We have all the voltages at the test ports except the one with -27 volts and can’t figure out what’s going on… that specific one is only going to -11. Is there any other place we aren’t looking where it would tell us what the voltages should be at different test points?

It will say on the schematics but there should be a +27, -13, and -27. If the -27 and -13 or more than 14 volts apart there are issues. I'd need to look at my DCC books to say what they are specifically.
