So just to be clear, the actual problem is that you're applying a load (robot is enabled and motor is spinning) and the reported current is zero. Is that true on all channels or just one? I mean if you move the load to another channel do you see the same problem.

The reason it was reading 1-2A before is because that is the raw output of the current-sense. It needs biasing (just like a gyro). The latest firmware zeroes it on boot (also like a gyro). But with either firmware, there should be a change in current, unless the current load is too small to measure. A free spinning motor with no load may draw 2A or less (which is in the noise floor). Remember this device is meant to handle/measure large loads (40A and up).

Are you using a Talon SR or SRX?
