You have an "OPEN" in the "BLACK" wire that goes from the "LATCHING CONTROLLER" to the water pump. There is a 4 wire harness plug that connects the 4 wires of the "LATCHING CONTROLLER" to the main pump harness - when you unplug and re-plug this harness together the "PRONGS" on the "LATCHING CONTROLLER" harness plug will force out (move backwards) some of the prongs on the main pump harness that creates an "OPEN". I think that may have happened to you. The "LATCHING CONTROLLER" provides a "GROUND" to the pump to turn it on. You can use a jumper wire from the "LATCHING CONTROLLER" BLACK (LOAD) wire to the Black pump GROUND (LOAD) wire to test this. If the pump still doesn't run with a known good jumper - then your "LATCHING CONTROLLER" module is bad (which I doubt is the case). The low voltage reading is correct as the diodes in the "LATCHING CONTROLLER" will make the voltage to the POSITIVE feed appear low.
