Nebraska | try a new power switch. the yellow light power switches seem to get some "age" in them and introduce extra resistance, undervolting the nav controller and therefore underpowering the valve command. I'm suggesting this because 1, its a very quick and cheap fix. 2, the system worked fine and is slowly becoming lazy. Calibrations don't usually change if it's been running fine for a few years. What the heck? i've seen this before. It cost me 3 weeks of troubleshooting. just give it a try. If I'm wrong you are out what $20? | |
