That is how my problems started. A couple of blow fuses (correct size), then freezing. Sometimes the ball would go down.....some times it would not. Sometimes it came up....sometimes it didn't. Lots of fun hand rolling the rigger spool when there is a 15 lb weight 100' down there and rigger dies. To be honest I never contacted Cannon directly as I do not have the time to sit on hold and deal with the issue during business hours. I believe there is only a three month warranty on the units. I wish they had odometers on them as this might help prove how little they were used. The overhaul from manual to electric was performed during the offseason so by the time the riggers are actually used come spring they are already out of warranty. Again, these were NEW everything except the bases, and booms. One of the spools I ugraded to a stainless model so even one of those was new.
