I have a 1988 Motorguide Brute 750, 12/24 Volt with foot control. It has five speeds, but it only works on speed #3,4 and 5. There are two red wires from the pedal; of which I connected one to the battery. Where does the other wire go??? To the same battery or is another battery required. Does this other wire for speed #1 and 2??
