Heating up

Hi EveryoneI have the new Ardupilot with Shield. When I plug my ESC into it - it gets hot. The ESC gets really hot and also the Ardupilot right where the ESC plugs into it. I dont think its a building/soldering issue because Im pretty good at soldering and also this is the second one to have the same problem. My first one had the same issure so I thought I did something wrong - so I built a second one and this one is doing it too... Any sugestions?? Thanks for the help - Oh I forgot to add that the lights are coming on and it apears to be working....

  • Same ESC ,same problem? Two different boards? Have you used this ESC before? I know --alot of questions.
    See if the ESC gets hot by its' self. Could be a bad crimp job on the ESC's connector. Those very thin stands of wire can get loose and short out. Look with a magnifier. I can't even solder without one. That's got to be it. Just enough short to not fry the regulator in the ESC.
    Check the + & - pins on the ESC with a meter. Look very closely at the back side of the connector thats getting hot.
  • Hi Tony,
    A photo of all or both the boards( close up) might get some help from some one here, Like Chris said , u might be making the same mistake in all three, it is easy to over look or assume some things., the two reasons I can think of is thin wires and shorts, soldering burrs or solder left over struck between voltage reg pin/pads etc, u have smoked( V.Reg i guess) at least one board from your description. If you have any one else good with electronics and circuit tracing , it would help with separate pairs of eyes ( believe me it does even if they may not be as good as you, they spot some thing you assume is right), We would like to help if you can post some clear pictures( board close up , wiring harness etc). don;t forget to look at all the loads( servos, esc and other items connected etc), did u use the same esc in all the cases, Esc gets warm to hot but not the way u describe. Did you buy the boards from the same batch/ same lot? Any chance of having polarity issues. good description all the components with brand names( bat, esc, servos gps, etc will give clear idea to guys here and resolve your issue. Good luck.

    That shouldn't happen--mine doesn't get appreciably hot. Almost certainly a short somewhere or you're plugging in something that either has a short or is creating one.
