Weird behavior in our code

It is the example compressor code. I'm opening the Compressor in DIO 1 and Relay 1, and setting the RefNum to Compressor. In Periodic Tasks, I am doing a RefNum Get (Compressor) and feeding that into the Compressor Control Loop.

What do you see the indicator doing when you completely disconnect the pressure switch? If it still says the switch state is false, there's something very wrong. Either the hardware (or the cRIO image) is faulty, or your code isn't reading the input properly.

I'll check that today. I'll get back to you later.

BATT doesn't come on. 5V and 6V is on, though.
This is our 3rd Digital Sidecar. I highly doubt all 3 are bad. The new one we got in the KOP was bad because 6V wouldn't come on. We know we are supplying 6V because it showed up on 2 other Sidecars and we checked it with a multimeter.
