I've been having trouble with my black tank reading anything. I did put in a new sendor a few year back so I hope it would be still working. I am not understanding how the wiring for the sendor works. I pulled and repaired the fresh water tank sendor and it had 2 wires to hook to, but I only see one wire back at the black tank from the GMC wiring, but the sendor has 2 wires...am I not understanding someing on this, shouldn't I have two wires to hook to from the motorhome as the same for the fresh water sendor hook up?
