If your esc is flashing red, the forward/neutral/reverse endpoints need to be programmed.

thanks ..ok so i activated the flap mix on my radio and set the end points on 0 to 100% and pos 1 is zero and pos 2 is 100% .removed the red wire from the ecs to the truck receiver so its getting power only from the battery pack on the trailer ..the esc flashes red but once i flick the swicth it goes solid red and the dump box goes up at a good pace and when i flip the switch back to 1 it stops ..and when i flip the switch to 2 it goes back down but very very slow...Now i have the down pos at -100% could that be why it goes down super slow ar because i am using a 7.2 v battery pack .This screw drive can run on either 12v or 7.2v ..would a 12v make it run faster and will it damage my receiver in my truck..i have a mfu in the truck ? thansk guys for all your help and suggestions btw
