Default Motor goes full throttle when car is turned off

So, this is weird...but whenever I turn off my RC car the motor goes full throttle. It's not even when I turn off the TX. If I switch off the ESC it just starts going. It is a Novak 410 HPC, its a pretty old ESC but it just started doing this today.

Did you try recalibrating it? With the ESC off it shouldn't be receiver any signal/electricity/anything

If one of the capacitors came undone would that cause the problem?

So, I tried recalibrating it, and it is still doing it.

Does your Tx have a failsafe built in? On my MT-4 if the failsafe is set incorrectly it will go to full throttle when it's turned off

Yes, it does have a failsafe, I will try that.

That did not work either. I don't think its a Tx or Rx problem. I'm not sure what it could be.

Does the ESC work properly when it is on? If you are short on money I would just leave the switch on and unplug the battery to turn it off.. but the best solution would be to replace the ESC I think.

Mine does the same thing when the car is on. No input from me and the motor will just go balls out. Interested in what the problem could be.

Yes, it works perfectly fine when the switch is on. I guess I will just take your advice and do that!

Yeah, I really want to figure out what the problem is, just because I am that kind of guy. I like to see what went wrong.

It's very likely something internal to the speed control. It's close to 20 years old. Can you name one electrical anything that you still use today that is that old?

It's an ESC failure. I just had a LaTrax Rally ESC act the same way. It was off but plugged in and occasionally the throttle would blip.

My toaster is from 1953. My car is from 1965. My home stereo system is from 1990.
