I have a new MH installation of a Multiplus-ii 2x 120 and cerbo gx and a touch 50.
It has been working fine and started buttoning everything up an decided to do a little load testing around 2kw with a 15A shorepower limit.
Now AC Input 1 and AC output 1 not displaying any power usage on touch 50 or vrm, even though everything seems to be working ok. Cerbo GX on firmware v2.80 and multiplus v4.90 to get rid of pll hum issue.
Hooked up MK3 and AC output shows power usage but AC Input 1 shows nothing.
Problem very similar to this link: Https://community.victronenergy.com/questions/89979/multiplus-ii-ac-input-suddenly-0-watt-on-gx-touch.html
Anyway, have done a lot of searching and issues like this seem to be a common problem, but can't seem to find a solution. I'm thinking maybe it's a hardware issue with the input current sensor.
Any help would be appreciated! Btw, it's not the data cable, hooking up the MK3 proved that.
