Seeburg 100C Scan Problem

Hi everyone,

I'm brand new to the jukebox world, having just purchased a '52 Seeburg 100C for my father for his birthday. I've run into (or rather, caused) a problem I'm hoping you might be able to help me with.

I purchased the jukebox knowing of a few problems it had and in an attempt to solve those issues I created a worse one. Everything was working except for the selection cancel system; if a selection was made, the selector would scan to the appropriate position, load and play the record normally (though since the cancel system wasn't working, it would put the record back when finished and immediately reload it and play it again).

As I was testing and checking some different things I had unplugged the 11-prong plug that runs to the Select-O-Matic mechanism. Unbeknownst to me, the center pillar on the plug that forces you to insert the plug a certain way had broken off and I inserted the plug at the wrong position. This, obviously, wasn't good. It blew two bulbs that I know of (the one behind the "Select-O-Matic 100" window on the plastic cover and the one highlighting the odd row of numbers in selection play indicator). The main issue is that it will no longer scan on it's own, even though selections have been made (which I confirmed by moving the pins to the outer "selected" position manually). By pressing the Scan service switch it will scan manually, but stops as soon as I release the switch. And if I get it to stop on a selected record, I can get it to load the record and play, but there is no longer any sound coming out of the speaker.

I tested all of the fuses and everything seems to check out there. I also checked the Motor service switch thinking that might have been damaged, but that seems to be fine as well.

I'm sure something got fried or fused together, but I'm not sure where to even being to look for it. Any thoughts on where to start? I've downloaded the service manual so I can reference that for any of your suggestions, but I'm brand new to all of this so I might not know any of the acronyms or lingo.

Thanks in advance.

At this point there are to many possibilities as to what shorted by crossing that plus, we would have to narrow it down. The first as you said would be the fuses, are you sure they checked out ok?

Any way, with a unit that old, you should rebuild (CAP Kit) the AMP and Receiver anyway, even if this did not happen. I would start there first.

aScott,
First, I would advise you to purchase the Service Manual Package" offered by the "ligit sellers" listed above, in "New-used--Where to find--". Most "downloads" are very lacking in info. I would also humbly suggest that my Seeburg Mechanism Guide, may be useful (PM me to purchase, if you wish).
Fuses are not in this equation -- but you should be sure the correct type/size are installed in you phono. The model C phono takes a 5 Amp in the "A"position, a 3 amp in the "B" position, and it may say a 2 Amp SB in the "C" (open) position--however, that should be reduced to between a 1 and 1.6 AMP SLO BLO.
Power to your motor is derived by any pin being pulled in the SA Unit (SAU) (aka "pinbank"). A washer is slid across the grounding bar and the contact going to the play control relay. This contact is wired from the SA unit on a single wire ( usually brown ), which is connected to the large cables coming from the SAU, and the Electrical selector. Both ends are "broken out" near the top of the lower door, and are connected together with a metal "bayonet" type connector. I sounds as if this is either dis-connected, or not making good contact--
