Internal schematic diagram of the electrical module of the Dalian Empire TRG meter?
Thread Content
There have been multiple instances where the pump does not start rotating and the current level does not drop. In the end, the problem was resolved by replacing the TRG electrical module. Does anyone know the internal diagram of those 5 wires? The stator insulation and DC resistance of the pump show no issues at all.
It’s completely impossible unless the wires are connected incorrectly.
