RC receiver help
April 16, 2011
I have a controller and RC board from an old rc car with tank style steering. I was playing around with getting it to control one of my bots, but i cant seem to get the wiring right. I'm pretty sure that i have the wires to the motors right, but i think i may be missing a wire. i can only get one wheel/tread to go in one direction at a time. There are four wires that correspond to 2 different points on the controller board. if i remember right, i am the one that soldered the wires. MB1, MB2, MA1, MA2. Then there is a VCC2, and a Ground.
I think the VCC goes to the battery pack, the ground to the battery pack, and the other 4 go to the motors right? Shouldnt there be some sort of power conrol that taps into the battery and ground lines? I know that i can make this work, i just cant figure out what im doing wrong! I am including some pics of the board. the red and black wires are all soldered to the connections mentioned above. someone Please please please help. I know its something stupid and its driving me insane!
