Diode test for Checking AKD Output Stage (X2 Connector / Power to Motor Phases)

Using ohm-meter or diode-meter:

Positive (+) lead goes to DC+ (X3 pin 3), negative lead goes to U, V, W (X2 pins 4,5,6).
Expected results are an open/high resistance (MOhm) reading.

Negative (-) lead goes to DC+ (X3 pin 3), positive lead goes to U, V, W (X2 pins 4,5,6).
Expected results are a low resistance/possibly short reading.

Positive (+) lead goes to DC- (X3 pin 2), negative lead goes to U, V, W (X2 pins 4,5,6).
Expected results are a low resistance/possibly short reading.

Negative (-) lead goes to DC- (X3 pin 2), positive lead goes to U, V, W (X2 pins 4,5,6).
Expected results are an open/high resistance (MOhm) reading.


If you obtain results other than those indicated, check your wiring.
