Mamba X no beeps or sensor

[Mr. Crawley EC]

I've been using my mamba x for a while with no issues, with a 2700kv Puller Pro and 4s.
Yesterday I put the whole system on another truck and I don't get beeps anymore (no cell count, arming or warning beeps). Also any of the sensor options stopped working wired or Smart Sense (no wire).
I get throttle and lights, but it works as if has no sensor at all.
Tried everything, updated and checked every option one by one and NO LUCK.
I know it's the ESC because I tried it with other motors and I get the same thing.
Any advice ?

Try reseating the esc wire harness for the sensor, or cleaning the contacts/pins, sometimes there is corrosion on the pins on the esc causing unstable or no connection.

Thanks for your answer, already did that and no luck, besides I have this no beep problem that's driving me nuts!

New harness? Idk I'm having trouble with mine too. My aux is dead, as soon as I power it on it had the aux glitch error beep. I checked everything, loaded an older version of the software, tried different radio, motor, new harness, nothing seems to work. I just disabled it all together now. It a a shame. I feel like castle is having qc issues recently or something. This current mamba x I have was bought in late 2020, my first one from 2018 has been flawless. My Las suggestion is just reach out to castle directly.

XD, I’m not an expert at anything, but a few things that may be worth a lookie lookie. Did you recalibrate the esc and radio successfully with each radio that you tried? You mentioned loading a a different software version. When you updated it did the pc, laptop, or whatever you used notify you that it downloaded successfully (and did you recalibrate radio/esc each time)? I haven’t spent a lot of time programming my Castle escs, but I know you can shut off beeps and change drive modes (sensorless, sensored, etc). If you didn’t already I’d go in and check all of your settings including cell count, cutoff voltage, beep/warning chimes, drive mode. Might not accomplish anything but only takes a few minutes. I wish you good luck ����

Try rolling back the firmware. Then moving back to the current firmware.
