Re: Having an AC Power Issue
At least now you know where to tackle the issue. Good luck.Update for 19-Oct @ 9 am
I spoke to George at Precision Circuits. Real nice guy. I barely got into my story and he told me I could stop - he knew what the issue was. He believes that their 'current sensor' has been blown by a dead short on one of my branch circuits. His theory makes sense to us as we measured accurate, expected current loads (amp clamp) when the PCS display read 100+ amps, then shed all 7 controllable loads.
I believe the dead short branch circuit is the WH. My "theory / guess" is that perhaps a wire nut has come off inside a metallic junction box on the WH and is shorted to the box - thus, dead short. I will tackle this first when we get home.
Heartland has ordered a replacement PCS control board from Precision Circuits to be drop-shipped to my home for self-install.
Incidentally, George told me the slow "heart-beat" like red LED on their control board is a good sign whereas a fast flashing red LED is a bad sign. So, while the control board is functioning, the connected "current cups" are blown and are giving the PCS false readings.
