Rockola 1454

Hi All

I have been restoring a Rockola 1454 for my wife. When I started this project everything was working. 

Yesterday I placed the mech back in the cabinet and powered it up. There is a wire attached to the pin bank and is a wire that goes to the plug that plugs into the Control Box Assembly that is located on the right hand side of the cabinet just behind the title strip drum. I have attached a link to the wire that is now detached. I have also attached a link of the schematic that shows the wire in question is coming from pin #9 of the plug, is a white & brown wire, goes to a wire nut connector that I cannot locate and then goes to a part that I am unable to identify and have circled on the schematic in hopes you can identify the part so we can hook up the wire to that part?????

I know that wire was attached to the pin bank as I had to cut the wire to remove the pin bank and then re-solder the wire when I put the pin bank back into the unit, which splice you can see in the picture. I cannot figure out where the wire was attached to the pin bank at?

A friend of mine thinks that someone altered the original wiring as shown on the schematic is why that wire was attached to the pin bank?????? and als thinks we should attach the wire to the part that is circled that we need help identifying, would this be a good idea????

At the present time, the pin bank will not work at all, the keyboard will not make any selections (makes clicking sounds), the record load switch will not cause the record carousel to rotate to load/unload records and the program button will not cause the title drum to rotate?????? I am thinking all these problems are related to this wire??????? 

When I first powered the unit up after installing the mech, a pin must have been tripped. A record loaded and played and as the record was being returned to the record rack I heard a sound like something popped. At that point I could not get anything to work and so I started inspecting the unit. That is when I discovered the wire now was not attached to anything.

Here is a link that shows the wire in question: http://s1074.photobucket.com/user/dghup ... 7954525662

Here is a link of the schematic that has the part we need to identify circled: http://s1074.photobucket.com/user/dghup ... 0487216979

Any ideas you may have would be greatly appreciated.

Progess being made, I grounded that loose wire and now the pin bank and mech will operate and play a record.

Problems remaining:

1. Program button will not cause the title drum to rotate? (Resolved contacts not being properly made has been corrected)

2. After last record is played, the carousel will not stop rotating and go to park? (Loose wire connected to inside of pin bank that is common point for all selector levers, problem resolved)

3. Due to title drum not roating only some of the selector buttons work? (Resolved title drum rotating)

4. Selections are not being canceled after playing. (Resolved soldered wire back on at cancel solenoid )

Hi Darrel,
Does that model use "washers"under the pins (like the "pin-bank style" Seeburgs), or a "scan control unit", to operate the motors ? Ron Rich

Ron

I have been told by a reliabale source that it is "Washers under pins like Seeburg".

Darrell,
if that's the case, I would ASSUME that the wire you connected to ground, should connect to the washers under the pins, and a relay, somewhere--this would be the cause of continual scanning--
Ron Rich

Ron

Thank you.

I found a wire on the cancel solenoid was not connected, soldered that in place and it now cancels records. Carousel continues to rotate, will see about "connect to the washers under the pins, and a relay, somewhere" and see if that will resolve the issue.

Hi Ron

All problems are resolved with the exception of that pesky wire Here is a link to the schematic forthe wire.

http://s1074.photobucket.com/user/dghup ... 9762167254

The wire operates the DC Start Relay Coil. It connects to a common point on the pin bank that would contact all selector levers. When the last selection has been played and record is returned to the rack and no other selections are made, as the gripper arm releases the record the start relay contacts open and the carousel stays parked.

So I need to know if you or anyone would know where the point is on the pin bank that connects all the selector levers where I would attach the wire?

Darrell,
That would be the "grounding bar", that a washer touches, when the pin is pulled--don't know physically where that connector is in a RO, but would assume there is a "lug" for it somewhere---Ron Rich

Ron

Thank you, the search is on!

The final problem has been resolved, thanks to Robert that had a pin bank he could look at. I had to remove the pin bank, open the pin bank up and solder the loose wire to the common point for the selector levers. It is back in the machine and is opeaating fine now. Apparently, the popping noise I heard was the result of the wire becoming tangled in the Carriage Assembly as it was rotating and the Carriage Assembly yanked the wire out of the pin bank!

Thanks to all that assisted me, especially Robert.

ewu--Ug, reminds me of the sound I heard when they were "pulling" my teeth ! Glad you "found-it !!

Ron

Sorry to hear of your loss, I have taken better care of mine

New problem I am searching for a 1 ohm 5 watt fusible (cement/ceramic) resistor that took a dump in the accumulator. Anyone got one for sale or know someone that sells them?

Hi Darrell,
I took GOOD care of my teeth--but my darn jaw( as well as others) bones are poor--only had four filled teeth in my life !
As for a "fuse-able", or "fused" resistor--I have axked people with much more knowledge then me what that iz--I have NEVER got any answer then either "no different", or "use a regular one". Hopefully "someone" has the correct answer, and we can both learn something "new"-- Ron Rich

Morning Ron

Terrible how we seem to wear out!

I was working with a selection issue, common keys 13, 53 and 93 and keys 90 and 119 will not activate the pin bank. I can manually operate the pins and the selection will then be made, not sure of this with the90 key. I had cleaned the key stems and channels they slide through with some Deoxit and was rapidly actuating the keys when the 60 year old resistor gave out, better the resistor than me

In your valued opinion, if I use a regular resistor would I be wise to place an in line fuse at that location? If so what size and slo blow/fast blo?? I assume (not always a good thing to do) the original was designed to give out before damage could be done to other parts??

Also, if you know, I see on eBay a 2 OHM 5 Watt cement/ceramic resistor, would that be to far off tolerance for this part?

Hi Darrell,
Yep--iz wore out !
I really don't know how to answer you, on this one--I am hoping someone else can--
