This year is the first time I have seen failures (Jim B) and then I was another one at the Abilene and Kinder Rallies (same rig, but didn't fix it until Kinder). I do know that the motor on my 2018 LM is a lot weaker than the motor I had on my 2014 BH (and the cord is two or three feet shorter). I guess they got a different vendor.
Same manufacturer but apparently some redesign.
Shoreline is the manufacturer. Shoreline is owned by TRC. TRC is owned by Southwire.
I think it was Frank B that "may" have fixed my old reel by "adjusting" the motor shaft. I think he used a Crescent-Hammer and knocked the shaft back into it's proper depth. By being slid out of the motor slightly, it caused the attached sprocket to be mis-aligned with the sprocket on the reel hub. When the motor ran, the chain was put in a bind and came off the sprockets.
We (I watched as Kevin W and Don S) replaced my reel as I was carrying the new one with me. New one works well.
Once Frank beat my old reel into submission, we were able to provide DC power to it and reel up the cord. I am storing it in my garage for either a hot spare, a gift for someone in need or to hack the cord off of it and make a 50 amp extension cord from it.
