Hi there,
i realized today that one of my two focboxes has a really bad input voltage accuracy.
Here is a quick graph showing a comparison to the other Focbox, not quite accurate since the values are just the result of entering “volt” in the Terminal followed by arrow down plus enter and it took place one at a time.
What is the consequence of this? Is this a symptome of a common error, maybe loose caps? Can I still drive with it or does it need repair?
If it rides without problems (errors, cogging etc) it should not be a very big issue, what were you powering it with? Battery or some other power supply? You could also try to spread the pins on the XT connector to put a bit more preload there but assuming it rides without some issues that should not be the case.
Was the measuring done under load?
Not for the above diagram but the voltage indicator in metr jumped rapidly when I drove. It worked but I had a bad feeling about it so I didn’t drive a lot. I replaced the focbox with a fsesc 4.12, now it’s working. The fsesc has no fluctuations at all, the left focbox has little but no huge spikes like in the diagram and it doesn’t affect metr.
