OK so I have been using this for awhile now and never had problems. I run a cord from 3500/4000 genie to 7 250 mh then plug the converter into the last light, converter to batt and troller to batt,. All the ends of the wires in the head of my motor guide 55lb melted and stopped working, so we hooked a 35lbs Minn koto up and the brushes got so hot they melted out of the housing what is happening. Have to figure it out before I try another.
