I have a R10 Pro 160 amp esc, It seems to only work when it feels like it.

I have tried to isolate the issue when it does work by plugging the servo, then the pt and even the sensor wire to see what might be causing the issue.
Nothing seems to just make it stop working.

When turned on it doesn't get any power/lights and at other times it comes on and fades out kinda like a brown out and rarely it turns on and functions properly but once its turned off then back on it doesn't work again.

The only thing I have not replaced are the capacitors and @ 20 plus dollars I'm hoping to not have to replace them.

Any help would be appreciated.
