rock-ola 429 magazine-gripper motor

Hi

I am creating a new topic because my old one seems to be fixed. http://www.phonoland.com/viewtopic.php?f=3&t=5643

I now have another problem, the arm gripper is on the home position and the cam groove in the switch 1.
when I run it on scan with both motor plugged in, the turntable turn only and 2 fuse blows (selector and gripper).
when I run it with the gripper plugged off, the magazine finally turn great.
I suppose that the gripper wants to turn at the same time of the magazine but the jukebox can't power enough these two and fuses blow.

that happened after installing the gripper back after cleaning. I may be accidentally touched something I don't know.
any ideas?

Thank you

Does this happen when the lever is on open? Possibly check the interlock relay and specifically microswitch 1, it breaks the motor when a selection lever is found and closes a circuit to the gripper motor and starts the whole transfer cycle, i would check the micro switches, just in case something got loose when you dismantled the gripper assembly, make sure the gripper motor is fully wound back for the start of its cycle. Check the motors are plugged in at the correct polarity. Micro switches need to be checked with an analog meter to determine if they are working properly

thanks for you reply

again it was a bad wiring in the motor..
now it seems that the gripper is too tight I can barely turn it manually
I lubricated the gears after cleaning.
is there something I can look at or loose

thanks

Hi
if the motor is loosened (usually three hex bolts) you should be able to manually move the gripper assembly fairly easily, there most be something that's stopping its movement maybe after you assembled it, the gripper assembly is fairly difficult(for me anyway) to dismantle and assemle, i usually have one side by side for reference
