Dave,

How long has the Tailtwister been in use ?  It could be something internal causing the intermittent turning also.
For a permanent fix to the terminal strip problem get one of these connector kits below.  The old terminal strip is removed 
and replaced with one of these connector assemblies.  Then you can unplug the cable easily.  Nice gold plated contacts
that won't rust.  If the terminal strip is rusty,  you might be abe to temporarily clean it but it will not be long term solution.
There are replacement original terminal strips available for the Tailtwister but it makes sense to do an upgrade.

Now having said all that, if you are going to do this upgrade, it is best to remove the rotator and work on it in your shop.
Then you might as well do an overhaul.  They are easy to overhaul, replace the bearing balls, regrease, etc.
all the parts are pretty cheap on MFJ's site.  There are some good videos on You Tube for doing the overhaul.
