381RBOK (or any with multiple black & grey tanks) panel reads wrong
My 381RBOK has 2 black tanks and 2 grey tanks. All of my indicator lights read the same. Both black tanks are 3/4 full, both grey tanks are 1/4 full, no matter how full or empty they are. If it was just he black tanks acting up i would buy it being the tank sensors, but with the independent tanks reading incorrectly and the same levels, it has to be a common link somewhere. I've changed the panel 3 times, so it isn't the panel. Anyone else having this?
The only other common link i can think of for all the tanks is a ground, but don't know where it's ground yet.
