Notorious ESC turning on and off, not pairing with transmitter

[Briggs]

I left my truck for 10 mins or so, on while wrangling some kids. The wife said my truck starting making the startup sounds over and over…. Now it doesn’t work, anybody have this happen? Do I need to re sync my radio and receiver? Or something weird with the ESC?

What truck you got first?v4-v5? May wana reset recalibrate esc. If that doesn't work unplug your servo. I bet your servo went out. Its common for the pos spekrum servos to burn out.

What voltages are your cells at?

 

[Briggs]

V5, I just checked again. The ESC is blinking red and then I turn on my transmitter and it shuts down

What voltages are your cells at?

Both 3s batteries at 93%

How are you measuring 93%? I ask because if you had a bad cell, it might not be reflected in that total. Do you have a lipo checker?

Yes I’m using a little cell checker. I was hoping I got a low voltage as well.

That is the exact one I have lol

Cycle thru the cells and see what each voltage is.

Unplug your servo and plug in another, boom problem solved.

Thank you, ok I’ll go through and see if any are low

Ok, they all look ok. Nothing crazy low. I wonder if something has happened to my throttle adjustment??? It is very strange, I turn on my esc on the truck and it goes through normal startup process with all the right beeps for punch etc. Then I turn on my remote and the esc LED turns off. No throttle, no turning servo. I guess my next step is reset and start again?

The transmitter power is supposed to be on before the ESC.

It doesn’t even go through the process that way. No LED and no beeps or anything

Well then something else is wrong. Transmitter should always go on first, then ESC. Must be a bad radio or something.

Guess so, thanks for your help. I’ll try re binding and the setup process again and see if that’s it

Did anything work? Do you have the stock servo?? If so plug a different one in.

My money is on a bad servo as well. Unplug the steering servo and see if your problem goes away. If yes, get a new servo, preferably non-Spektrum.

Just did it, unplugged the servo and everything worked as it should. Plugged it back in quickly and it all stopped working again. What a piece of junk that is, I have had my truck for like 2 months. So do I grab the 35kg from Amazon?

 

[TriggerHappy]

What i said to do last nite

By all means you can get a new one under warranty, but yes I'd get a cheap one from Amazon.

That’s what I’ll do, I’m still going to get one under warranty as another backup - it’s free why not I guess
