Rhino, had the same thing happen to my work rig. The intermittent work, then stop. Then clicks. Then fine. Repeat. We always had 2 batteries ready to go, so no issues there. When it finally refused to work by the remote, I tried power straight to the motor. It lurched a little and that was that. After exhausting testing options, we just bought a? Western? I'm not 100% sure. It was a similar build and has been working since( 2 years). When the Harbor units work, they work great.
