Hi all; I am getting error code 954 (line voltage lost sync) on the VDS, and flashing red lights (no blink code) on my UMC, even charging at 24 amps (on my 40 amp circuit) after charging for over an hour, sooner at 32 amps. It does not respond to the reset button, but after sitting a while unplugged the UMC will show green again without pushing the reset button. This is my second UMC in the month since I got my (CPO) Roadster by the way... I still have my G.E. Wattstation left over from my Leaf, and am wondering if maybe using it with a J1772 adapter would result in smooth sailing. But - I don't know what exactly if anything was wrong with my current, or what to have an electrician look for. I certainly wouldn't want to risk damaging my Roadster because the Wattstation would let too much variation in current pass through! The Leaf (now gone - no room for both) never had a problem charging through the Wattstation (same circuit), by the way. (I am considering this notion because I already have the G.E., as opposed to getting a Tesla wall unit for another two grand, and don't want to do that only to find out it's a problem with my house circuitry!) Anyone have any experience or suggestions? Thanks!
