    Is the Blue Wire Positive or Negative???

    OK, I am an idiot ... but I am so new at this that I've got a lot of dumb questions.

    Just bought a used motor from one of my buddies. The stock ESC has a black (negative) and red (positive) wire, but the motor has Blue and White. Which one's positive, and which one's negative? I don't want to reverse these and fry something ...

    Lightbulb I'd ask your buddy for the Directions!

    What's the name of it? Lots of these Motors have on-line manuals.

    BUT, if i had to guess. Blue is Negative, and White is Positive.

    darker color is always going to be the black(positive?)

    I wonder if other dogs think poodles are members of a weird

    Stampede101 is on top of it. Look for the marking on the endbell. Chances are he soldered the wires on so colors might not mean squat, as he could have soldered them in whatever order he desired at the time.

    Well first of all if u wire it backwards it wont fry anything, so no worriys there. If it is wired backwards the braking afect will work backwards.

    but look on the endbell of the motor and it should have a little "+" on one side of it that would be the hot side. If it doesnt not have the "+", it would make the most sence to me that white would be hot (same as red) and blue would be the ground(same as black) BUT i just got a APEX speedo that has white and blue instead of red and black and it is white=black and blue=red

    So all i can say is i would true it blue=black and white=red, if it is backwards change it, i have messed up and wired a few backwards and i have NEVER had a problem.

    headhunter556 is right on.
    It doesnt matter if you wire the motor backwards, the truck will just go in reverse when you pull the trigger. If that happens switch the wires and you are good to go.
    Most motors are labeled with a +, however te stinger and other silver can motors are not.

    Thanks for your help, all of you. I just experimented a bit, using your advice, and I figured it out.

    This board is GREAT for beginners like me!
