I have a 1991 motorguide esp50 24 volt (50 lb thrust) Brute compition dura amp 2 trolling motor that I cannot find parts or information on. I have called the company and several repair shops throughout our great nation to no avail. The part I'm looking for is the cuircuit board (WF157-06) or the scematics for this board. I blew a resistor in slot R16 (connected to the male end where the blue wire attaches and cannot read the color codes on resistor. It was completely black. Thank you
