We have an issue where two of our four motors will not spin. We can switch the two functioning motors with the two non functioning motors and then the two non function will work but the function will not. We have checked continuity from the FC to the ESC and have no issues. We have double and triple checked that the wires and their respective connections. We also built a second wiring harness just in case. We have replaced the ESC with a new one. We have tried a different PWM. We have tried different batteries.
When I look in QGC at the parameters for the PWM Out, I noticed a few parameters were in red. I’ve attached pictures for this.
We did try switching leads and it does reverse direction of the motors but it only works for operational motors. It did not cause inop motors to start working.
Hey @JNeaves this means that your ESC cant see the input from your flight controller. Can you double check that your connections from the FC to the ESC are solid?
If you pull the dupont connector from the flight controller from channel 2 and place it in channel 1, and repeat your test, does motor give 5 beeps?
Same for channel 4, if you pull the cable from the FC channel 3 and plug it into channel 4, does motor 4 give 5 beeps?
From the PWM Controller:
Pin 1: connected to all 4 ESC inputs: Green, Orange, Yellow and Blue, no motor beeps on any of the 4 motors.
Pin2: connected to all 4 ESC inputs: Green, Orange, Yellow and Blue, All 4 motors beeped
Pin 3: connected to all 4 ESC inputs: Green, Orange, Yellow and Blue, no motor beeps on any of the 4 motors.
Pin4: connected to all 4 ESC inputs: Green, Orange, Yellow and Blue, All 4 motors beeped
When moving the connectors around we can get the motors to beep if they are plugged into channel 2 or 3. If any motor is plugged into channel 1 or 4 it will not beep.
