Does anyone know what signals are required to run one of the 12 water pumps in a 1st gen Leaf?
There are 3 pumps in the vehicle and each has 4 wires. I measure one of the wires as being about 13V (slightly higher than battery actually). Other wires when measured with a DC multimeter showed fluctuating voltages between 0v and 10v. Could be digital signals, AC current, or who knows what elese. Lacking an oscilloscope im hoping somebody has the answer.
I'm trying to wire up the PTC pump so I can operate it with a switch in my EV conversion which is the 2012 Leaf in a 1986 BMW 325 e30. Hijacking the resistance heater functionality will be next
