Exclamation Losing power through DS.

So we've come across an issue of when we're trying to run our motors, the 5V light on the Digital Sidecar goes out and we don't get power to the DS unless we disable-enable the Drive Station again. Drive motors 1 and 2 are in PWM slots 1 and 2. A single motor is wired into PWM 3. A Servo motor is wired into PWM 4.

PWMs 1, 2, and 3, are connected through Jaguars to CIM motors. If we unplug the PWM to the single motor (PWM 3), the issue doesn't occur.

Also the drop in power only occurs when we push our joystick to the left. Right, Up, and Down the motors can be powered fully. We can push the joystick to the left about halfway before the power cuts.

We've exchanged our Digital Sidecar with two others available, and the issue still occurs. The battery is at 12.9 volts and doesn't dip below 12.5 when we're applying power to the motors.

We're using the NI cRIO-FRC with modules in slots 1, 2, 3, and 5. 1:9201. 2:9403. 3:9472. 5:9201. We've also tried exchanging the slot 2 module, 9403, with another, issue still occurring.
