I have a P70 control head and an EV-1 ACU 200 which has been working fine all season, but yesterday the P70 started displaying a no pilot error, and the menu/mode page is blank. I checked voltages on the ACU 200, and there is 12V on both sides of the main fuse, and the seatalk power fuse. I have also checked all of the seatalk connections and they are all tight. How do I go about troubleshooting this?
