Right. Thanks Mike.
I will change out the relay and then replace the controller if the relay doesn't fix it.

I have a feeling I shorted out the controller.

Thanks for all your help. I'll report back.

BTW I did swap the AC relay and the fuel pump relay and there was no change on the controller. I think I just flat smoked it - probably the circuit board in the rear.

Once I get the next controller in, I can go back to trying to figure why the compressor is not kicking on. If I am low on Freon, my gauges are not being truthful
