dump trailer hookup

[RCP57]

Could you not just split off your power leads and run a separate ESC for the dump removing the red wire on the servo plug as Mark mentioned? I don't have any experience with MFU stuff but that would eliminate it from anything related to the dump.

i do have a separate esc for the trailer and it has its own power supply also a nimh battery but i need to put it on a 3 position switch on my dx7 and i have no idea how to program it and which switch to use .so i plugged it in one of the ports on the truck receiver in aux2 and there is a switch on the radio that is labelled aux2 and when i flip it .nothing happens and the esc is flashing red ..so i am not sure but it looks like i need to the esc to show a solid green light

Maybe try plugging a servo into the aux 2 port on the receiver and then try to figure out the tx programming. I'm just thinking this is a simple way to test forward and reverse rotation when you activate your 3pos switch. What you are doing should work correctly though.

i have tried it and there is nothing..the esc is flashing red ..i think it should be a solid green to take commands ..i have binded before for a truck but never a something separate like this rcp57

You've tried a servo eliminating the esc for now? If everything else is working there must be a setup issue with the TX. I don't have a DX7 but I do have several other DX?? radios. This should be an easy hookup for you so something simple is being overlooked.
