Mod version 4707, I can't seem to get the power detector to work properly. An image of the settup:

Power is flowing, I can hear it from the electric heaters. The detector just isn't turning on.

At some point it might have changed where power has to be flowing through the block, though I'm not sure why that would be the case.

If you replace the detector with something else like an electric furnace, does it charge?

Yes, it instantly fills up. I tried with both power cut to the heaters and with it reconnected, and then I replaced it with the detector again. Detector just doesn't get power.

I assume the issue is because of the network's demand being so high that the amount of power supplied to the detector is rounded below 1. I made the power detectors take higher priority than most other consumers (probably not an issue because of how little power they use), could you verify whether that fixed the issue?
