BAL AMI S100 wiring diagram

[dazzathejukekid]

Hello

I am having a helluva time, trying to re wire this jukebox, I know that there is no wiring diagram for this jukebox, so I am going by the AMI H for guidance only. My stumbling blocker at the moment is the muting wires. The AMI H has two wires that feed from the mute button in the control box to a terminal box of some sort, and then from that box two wires feed to terminals 3 and 4 on my beam echo amplifier.

My s100 does not have anything in between the control box and the amplifier terminals 3 and 4, so if i directly wire from control box to terminals 3 and 4 its not going to work.

Obviously this box has simplified wiring to the AMI H, so if anyone can give me any guidance on the muting wires, then in think i may nearly be there with this box.

Kind Regards

Darren

Hi Darren,
The wire from the cluster of contacts as shown on the H schematic (CS contact 7, cut off switch, RR contact 2) where does that go on your S100? Does it go to the control box? That's what will switch the ground (earth) of the muting relay. In the Bal-Ami G80 which would have had the same Beam Echo amp, two wires are taken from the control box to the muting relay in the amp - one carrying the switched ground and the other carrying +ve DC supply. Can you find +ve DC supply in the control box?

This shouldn't be an insurmountable problem!

Darren,
I have come across a wiring diagram for the H that shows exactly how it should be wired, I will message it to you!

Hi Darren,
I did compose a message with the diagram but it seems to have got lost somehow, I'll do it again!

Hello Norman

Thank you for that diagram, I will see if i can make sense of what you have explained to me. I took a couple of weeks of from the jukebox as i was starting to make silly mistakes through frustration.

Thanks again

Hi Norman
The wiring of the mute circuit is different on the AMI, my S100 has a beam echo amplifier with an in built power supply, the AMI has an external power supply.

I am still confused.

Thanks

Hi Darren,
Well that's two of us confused! Let me just say I've never worked on - and I'm not sure that I've ever seen - an S100! The first piece of confusion is that if you have a composite mech. power supply / amplifier, that's not what is normally referred to as the BAL-AMI Beam Echo - I don't think Beam Echo built these. The Beam Echo amp was fairly similar to what AMI used in the H and I

The composite power supply / amp was used in the Junior and S40 - might you have been better using that for guidance rather thatn the H? In any case, I will PM you the diagram of the amp - what you need for the mute relay is just a switched earth (ground). I only have a paper copy of the S40 manual, not a pdf.

Hello Norman
That's spot on its the amp used in the S40. on that diagram you sent over where it shows TS1, the terminal strip, its terminal numbers 3 and 4 on TS1 that I think I am supposed to attach wires to for the mute relay operation. I had originally attached wires from the control box to 3 and 4 when I pushed the button it did shut off the turntable motor when keeping my finger on the button. P53 the four pin plug on the diagram, I noticed last night, the four pin plug that goes to P53, a short wire with a spade connection on it that was taped up for some reason, on the diagram it has text alongside that wire that was taped up stating(to mechanism junction box).
As you can tell I am finding this all very confusing.

Thanks
Darren

Hi Darren,
I'll try to have a closer look at this for you tomorrow. According to the S40 interconnection diagram PS3 on the amp connects to PS9 on the mech. and that carries the switched ground that will energise the mute relay (it also carries DC +ve and ground). It's not easy to work out which wire is which from the diagrams, it looks like I'm going to need to trace the circuits.

Hi Darren,
I have looked again at the S40 diagrams and it has defied me to work out which wire is which! PS3 on the amp connects to PS9 on the mech. These are 4 pin connectors but only 3 are used. The wires in the loom that connect them are red, orange and black. They carry +30VDC (red?), ground (black?) and orange (switched ground?). That switched ground from the mechanism should energise the mute relay. I will send you another diagram from the S40 manaual that will maybe help clarify things a bit. It might be a good start to trace which colour wire carries the 30VDC and ground.

Norman.

Hi Norman
Thank you, i will try to digest this info and see what is what, i will let you know how i get on, much appreciate your help Norman.
