I have a baffling issue with my cars ESC.
I'm running a Speed Passion Retention Pro in blinky 21.5 mode.
I was at the track today and all was well when I spun out and hit the wall, not hard but enough to slightly dislodge the battery pack so I pulled it back into the pits. Refitted the battery pack when another guy racing lent me his SP program box as I had a issue with the brakes not coming on properly, it was slightly different to the one that came with my ESC (that I left at home) but it seemed to work fine, I adjusted the brake settings and put the car back on the track, but no go. No throttle control, the steering works, the ESC was turning on with its fan running, just no drive to the motor. After 1 hour at the track of head scratching I gave up and bought it home, since then I've tried the following..

• Tried a different sensored motor, no good
• changed the sensor cable, no good
• reset the ESC and made sure it was running the latest firmware
• tried a different battery
• swapped radios over
• reset the throttle/brake parameters, still no luck.
• double checked the wiring

The ESC is only 1 month and has been use once before without issue.
Its in blinky mode but seems to be flashing faster than it normally does, but trying to rebind the throttle and brake parameters does nothing. The second channel on both radios do not seem to work.
The only thing I haven't tried is swapping to another receiver, not sure if that will do anything though.

Does any one have any advice?

By swapping Radios does that include the Rx?

If not check that to see if it changes anything.

Tried a different receiver still no luck, however a complete reset has some activity, it sounds like its trying to do something when I apply the throttle, just nothing happens.

Head scratching continues..

Have you tried your program box ? Some are esc specific in other brands.

Bad output board, needs to go back for service.

Yeah I think I'll have to send it back, I'm 99% sure I've exhausted every avenue...
Even updated all the firmware.

The motor has current but no power, not even enough to turn the thing over.

Let me guess no arming tone from the motor?

Yep not a beep. Tried a 21.5 and a 13.5..

Fixed it, a fricken bad solder on the ESC was the culprit..
