Did my esc just fry?

[Nimyad]

Stock exceed mad torque esc, about 3 months old. Been running it on 3s for a total of 10 hours maybe, it's gotten hot but not recently.

I just got my new chassis done and went for a test run for about 5 minutes with no issues, nothing got hot and everything was responding fine.

Went in to tweak my car a little and then plugged in the same exact battery and nothing. You can faintly hear the esc powering up and connecting to the tx but it won't go forwards or backwards. So I bound the rx and tx again, still nothing. Plugged in the nimh battery that came with the car and it'll go forwards really slowly, still no reverse.

All the trims are set correctly and I still have steering, but I have a bec so that doesn't really mean anything. So did I fry my esc or?

Also, the led comes on when you give it throttle in either direction, it just doesn't go anywhere

check the motor and wiring going to it. the esc startup tones are actually made by the motor and if you hear it faintly...

[Nimyad]

All the wires are good and the startup tones come from the esc. I plugged the nimh pack into it again yesterday and it drove around normally for a couple min, then I lost reverse. If I plug in the lipo all it does is the startup tones very quietly over and over.

brushed esc/motor? I was guessing brushless. is your lipo fully charged?

[Docwolf]

silly question, but are you sure your packs are charged?? this really sounds like LVC issue.

[Nimyad]

Brushed, yeah the lipo is fully charged, it wasn't fully charged before when it was working.

[envious8420]

if its working on nimh and not with a lipo, I would be checking the all of the solder joints from the battery to esc to the motor.
might have a bad solder joint that hasnt broken yet. if you have an ohm meter or dvom I think I would ohm each connection. You might find one that is really high compared to the others.
