Re: URGENT - No power from backup battery/PWM port voltage
 

I checked the pwm voltage with the RC off and also did not get any reading. so i think you were right about not getting any power because it is regulated by the RC.

I'm just posting this for closure.

We found the problem a week or so ago... somehow the backup battery was wired up backwards!

We were assuming white/positive black/negative, but somehow our cable's flipped.

All is good.

Whoa!! I thought the plug could not physically be switched around in the outlet. I guess I was wrong. Or did you guys damage something??

Re: URGENT - No power from backup battery/PWM port voltage
 

The battery's connected through a plug on the electronics board, which goes to spade connecters on the RC. These connecters were switched.

Thanks for letting us know what the problem was. Just one more "obvious" thing to look for in helping other teams!
