M3 and M4 no voltage

[Patnet]

Hi, I'm running into a problem with a new M4V2 board where brushed motors M3 and M4 won't spin. M1 and M2 are OK. The failed ones worked for a few minutes and have now stopped. There's no voltage on the pads when armed and with throttle. No solder bridging at the pads. All four motors work. Board isn't bricked. Any ideas?

Maybe you have disabled them on the mixing tab? It's the only easy thing to check... or maybe miscalibrated accelerometer and fc it's detecting the need to have them stop, but they should work at least at mot_min signal.. besides that it must be hw failure.

Hi Axi, thanks First thing I checked too. Mixing is all 100 percent.

When you connect the battery to the quad if you keep moving it as your connecting the level can sometimes be way off so you need to do a Tare. Once you have the level reset the two motors may run again.
