If I power up the esc normally, it will do the power cycle noise and get me lights as if everything will work, but just no power is sent to the motor (have yet to verify with a voltage meter), but I did try with a different (working) motor and had the same result... nothing happening to the motor.

If I try to hold the power button from when it is off, or on, to change any setting or program the esc, or try to recalibrate, that is when it turns to a solid red light and will become frozen at that light until battery is removed.

Also, if I unplug the battery to power off the esc, unless it (the battery terminal) is off for more than 10 seconds, any attempt to power up the esc will go straight to a solid red light.

I will get a few other sensor wires together and try more of them, just in case!

Need some tech help having some issue I can not figure out. Vtx8 with Tekin pro4 hd truck runs great for a whole heat then next heat on a landing truck will stop esc will flash red and yellow alternating lights. Have swapped batteries, sensor wires, battirie plugs. Motor connections are good can not see any damage to wires what should I check next motor sensor board? Somthing inside the esc getting loose? Yesterday's A main it did it on warmup lap restarted the esc and made it four laps until it happened again. Always happens when landing a jump.

I have a vtx10-r that I purchased brand new form LHS and I ran it 1 race night, I ran it in the "blinky" mode and it ran pretty well. It is in an AE b44.3 with a 6.5T reds motor at 0* timing advance. I took temps after every run and never exceeded 115*. After the racing, I asked a local fast guy at the track to take the buggy for a spin and help me with setup suggestions. He took it for 1 lap and pulled the buggy over to adjust the travel in my remote, after that the buggy has had no more drive at all. We reset the travel back to where it was and still nothing.

When i power the esc it will turn on with normal lights, but has no forward or reverse action. My steering works, so I know its not a dead receiver, but just in case, I tried with a spare receiver and it did the same exact thing. It has steering, but no esc action.

If I try to go into programing mode, it will get a solid red light that will never go away. At that point anything I do to the esc will not work. It will not even shut off, unless I pull the battery. I try by pressing the power button for several seconds and wait for the beeping, but it never happens and never changes lights.

I found this video on yt ( https://www.youtube.com/watch?v=p7Z_-G74ORo )and it is doing the same thing as mine, where it gets stuck on this red light and then is unresponsive to any other presses.

Has anyone else had this issue at all ? It is a practically new esc, so I have no idea what may have happened. Any help at all would be much appreciated!

I tried looking up this issue but have come up short on my searching, and I am sorry, but I'm not about to read 700+ pages of this thread to see if I can find the same issue on here, so I apologize if this has been addressed before, but maybe someone can help or point me in the right direction...

The amp spike is coming from either the motor (internally), motor sensor, or connection issue (with either motor or battery). The speed control is trying to protect itself from being damaged from the amp spike.

Things to try would include - different motor, resolder all connections (including any plugs), replace plugs (either on esc or battery side - maybe both). The fault is not within the speed control. Its trying to keep an outside source from damaging the unit.
