After pushing in a record number the write in motor spins and stops at the location of the pin....no limiting light flash and no striking of the pin on the write in...the read out motor will find the pin location bit will not strike the pin....when I move the pin by hand, the gripper will pull the record and play but then will not stop playing...the reset does not cancel the record and moving the arm will not cancel the record....i can press and hold the gripper reverse in the control box and it will return the record to the magazine and then start turning the magazine back to home....so it does not strike a write in pin and it does not flash the limit light after finding the pin location and it does not cancel the record..thoughts?
Are you referring to a 444 model? Failure to hammer the write in pin starts with the K4 write in relay. Have you reseated it and taken off the red cover to clean the contacts? If no, do this. Then leave the cover off when you put it back into its socket so you can see if it is actuating or not Then go and reseat the the selection molex on the front of the power supply and the credit unit. Then go to the credit unit. Open it up and clean the contacts of the ADR relay and the debit coil. Again leave it open so you can see if the selection impulse switch and debit coil work when you make a selection. Lastly, watch the wobble plate solenoid to be sure it is kicking in when the write in motor stops. Lots of possible causes of trouble here. Review sequences 9-11 in the manual. Reset the jumper plug on the front of the power supply as well. Then report back. We may have go thru the Rockola Jukebox Club group on FB to send each other videos. If you haven't joined this group, I would recommend it.
Thank you so much for this video ad I am chasing this problem with a Rock-ola 460. It would help if I could get a 25-30 volt supply to check relays. Can you share what you use please?
look for a transformer rated at 3 amps with a 24 VAC tap. Connect the two wires that supply the 24 VAC to a 6 amp or higher silicon full wave bridge rectifier. AC leads should be marked. The other two leads will give off DC, one positive and one negative. Use the DC leads to check the gripper and magazine motors in these jukes.......and the 24 VAC to check the write in motor. Contact me on FB Rockola groups for specific questions or better yet, join the Rockola Jukebox Collector group and ask specific questions to all. In my last video today, I mentioned a current limiting bulb which is a good idea to use when testing any unknown load, be it a motor or an amplifier or a power supply.
@@williamweisel2176 I have an idea- Why cant I connect to the 30 v output from the power supply and connect to the relays directly? then start back tracking from the relay with the 30 volt circuit to see where the issue might be?
I have an extra gray wire black 4 prong plug 4 foot long think it's for external speakers does anybody know
