Those readings seem normal, although I don't know why you get "no resistance" with positive on the control pilot pin (negative on earth).winfried said:- Pilot:
Resistance: 4 MOhm (+ on Earth), no resistance (- on earth)
Diode Test: no connection (+ on earth), 1.77V (- on earth)
? "No resistance" is "low in one direction", is it not?Since, stated before, resistance of the pilot-ground should be low in one direction, but is not.
I think that this is yet another case of "it's not the diode". So something not quite as simple.
Is it possible to make a measurement of the pre-charge resistors, equivalent to the below for the iMiEV? It will not be 9.4 ohm for the Leaf, since it has 3 resistors to the iMiEV's 2, but open circuit pre-charge resistors are a common failure mode with the iMiEV OBCs.
The 1/2 ohm measurement is when the relay is energised; ignore that for now.
