Default Rockola 440 Gripper and Magazine Motor Blowing Fuses

Robert, motors can be rewound, while that might be the most reliable
route, it may be cheaper to locate a known-good replacement via one of
the ad's in Always Jukin http://www.alwaysjukin.com/ D/L a sample
issue and look over the classifieds -the same sellers are there every
month.

As for the microswitches, if the motor isn't overtravelling and
jamming at either end of it's travel the switches are not the problem.

If you have a meter capable of measuring amps you might hook it up in
series with the fuse, but I'am pretty sure you have the classic
problem of excessive current drain from shorted armature turns.

The gripper assembly may be gummed up too. This will cause the motor to
draw more current than normal.

Turning the gripper motor shaft with your fingers should operate the
gripper bow through the entire cycle - picking up and replacing records
- without feeling like it is jamming up.

The gripper arm should feel slightly loose when resting, and the record
pin should feel snappy when it is picking up the record (at rest is is
solid). The gripper arm should drop when released not go slowly down
(indicating gummed up oil/grease).

Info on taking the assembly apart is he
