Re: Torsion Level System

Not sure what was going on to cause the melt down of the red wire other than no fuse preventing it from happening. When I questioned the limit switch and how it worked, it was after running the motor by shorting out to ground contacts A & B. Before either side of the switch touched a transverse bar, the motor stopped. I was concerned about over torquing the motor and screwing up the gear box. I discovered that the fuse had blown but couldn’t figure out what had caused it.

Eventually I found that when the levers were moving outwards the frame, the top on the rear solenoid would short out against the motor. I’m guessing this is what led to the wire meltdown. That it would rub against the motor causing an intermittent short, but not enough to melt the wire.

I lowered the solenoid a bit and the motor can now run from one extreme to the other with the limit switches stopping the motor. The TL system has a problem so I’m in the middle of troubleshooting it. It works once in a while so I’m guessing that the contacts in the Compensator are corroded. I’ll pull it tomorrow, test it and clean up the contacts.
