i picked up a bear tracker motor for my ytm dr , up to this point everything is fine except the rectifier(regulator) is missing from the harness, like cut off and gone. it has 3 white wires comming from the base and then a single red out to charge the batt and a black for ground. what i wanna know is can i use the ytm one? its different i know it has 4 wires.( red,black,yellow,white)but it only has one white wire in from the base and i dont think ill need the yellow wire.has any one done this or can offer any insisght. used parts place here want 75 for a used one....not gonna happen. and i cant find one for a big bear (same 98+)
