Help with Rockola 100 3

Hello,
I have a problem with my rockola 100 3.
The record will play but only if needle is placed on turntable.
It will not return when record is done.
I have looked at all fuses and they look fine.
I have the operation manual and notice that it will not run in normal operations mode.
When I try to move to normal operations, it just skips over that light and moves to the next.
Any help would be greatly appreciated.

Might be able to help-but need much more info--clearer--
What is a "100 3" ?
What do you mean --- is the gripper over the turntable or the record basket ?
Using the terms used in the service manual, will help greatly--

Hello,

It is the rock-ola 1000-3.
The gripper is lying flat around the turntable.
A record will play if I put it on the turntable.
At the end of the song, I must remove the record
or the needle will continue to run.
At the system 3 control unit, the normal operations
button will not light up using S1 advance.
The reject button on the back is not working now
either.
I am very new to this, so I appreciate any help.

Do you have the service manual--if so, follow the sequence of events, or the trouble shooting guide.
Gripper motor is either "jammed" or not getting power. If you don't have the manual---purchase one from a "legit" seller--listed above in "announcement--where to find--" Ron Rich

Thank you Mr. Rich.
I appreciate the help, as this is all new to me.
I bought the Service/Parts Manual from Victory Glass.
I am in Cleveland, Ohio and hired a serviceman from the place
where the jukebox was purchased. He tested everything,
but was unable to repair it. I have read many of your answers
to other inquiries and have begun to take apart gripper motor
assembly because the grease is dried up. The record magazine does not turn even in scan mode. The repair guy said that he tested the scan switch and it was good.
I can turn the small post on both the gripper and record magazine motors, but both are very hard to move.
I am able to move gripper over magazine, plug jukebox
in and the gripper will grab the record that is there for it, takes
it to the turntable and record plays, but will not return when record is finished. The only thing that I noticed is that on the Mech Power PC Board #54870-A, part # R-305 becomes very hot to the touch when gripper is bringing record to turntable and playing. It will then cool off
quickly when jukebox is off.
Thanks for any help that you can give me.

Hi
Haven't heard of a rockola 100 3, if its one of the rockolas from 429 up to 488, the trip blade when the tone arm reaches the end of the record should cancel the record, or else use the cancel button at the back of the machine.
If the gripper arm is stuck and you need to manually move the tone arm, there may be a problem with the microswitches or possibly the control box depending on the model of rockola. I would loosen the gripper motor and manually wind the gripper arm back to the position over the record basket, it wouldn't do any harm to oil the gripper assembly. Also check the gripper motor, i have seen motors that operate ok at the start of the sequence(ie gripping a record and placing it on the turntable) but stall when the sequence is just about to end, this might sound a bit vague but as Ron says you need the manual and study the sequence of operation

The Rock Ola 1000 was produced between 1987 & 1989 it was a 1050 remake jukebox.

I hope some of the other forum members can help you sort out the issue you have got with this jukebox. You will find that more than likely it will be down to the electronics, I would suggest that you find an engineer that can test all of your boards and power supply.

I have seen the RO 1000, however, I do not re-call seeing any marked "100 3", so I wonder ??
The 1000 has to be the "strangest juke ever made". It started life as a Wurlitzer 1050 "Nostalgia". At the time Wurlitzer closed, they sold it, and all jigs, dyes, and remaining parts, to a Mexican company, called "Sonata". Sonata assembled it using what was left of the original parts, but they started running out of original parts and began producing their own design "replacements". To put it "nicely", the quality went from awful, to worse, and as time progressed--"worser-er" !
Then one day--the cabinet shows up with a RockOla name tag on it, and RockOla 492 ( 100) guts.
Since I have no books or schematics on it, I don't know what that resistor is/does. If it's a "power resistor" (aka "sandblock") type, they are supposed to get hot--- See the schematic and decipher what circuit it is in---Ron Rich

Hi,

Thanks to all who took the time to help me,
I really appreciate it. Last weekend, I tested
as many switches as I could find and all seem good.
My manual is pretty vague in the troubleshooting
part, so I am having a difficult time trying to figure out
why I cannot run the System 3 Control Unit in Normal Operations. This weekend I will try to take apart the gripper assembly and degrease old grease.
Thanks again for your time, help, and knowledge.

How are you "testing switches" ? If you are using a "digital meter" be very suspicious of any that test good. Only thing that meter will tell you is if a contact is open --it will not tell you if a contact is able to carry current or not, even if it shows it "closing". A GOOD, analog meter, set on "x-1", is required for that.
Ron Rich

Thank you Mr. Rich.
I had read many of the postings and went out
and bought a good analog meter. I will continue testing this weekend. I'm just a bit worried that if I take apart the gripper assembly to clean, that I will not reassemble it correctly. I will take lots of pictures for reference.
Thanks again!

I only have needed to "dis-assemble" 1 of 100 grippers --takes some time, but 20 wt ND oil will usually loosen them up for me--
Ron Rich

Hi,
Is there any good way to get rid of the old grease
without taking the gripper assembly completely
apart?
Thanks,
KG

If it's the black, graphite type, the 20 wt will soften, and re-new it--if not, you are probably going to need "die-no-mite".
Ron Rich

Thank you Mr. Rich.
Some of it is black, but I also have seen
a yellowish grease stuck to some of the gears.
I'll dig in tomorrow.
