Hi,
I have a Kenwood DNX521DAB which will not power on. I have tried to bench test it by supplying power to the yellow and red wire of the harness and connecting ground to the black but my power supply goes into protection mode.
I suspected that there is a short somewhere in the wiring harness but all tests show that this is not the case. I removed the harness from the unit and using a multimeter in continuity mode, I pressed one probe onto the power pin and one probe onto the ground pin and it shows that there is constant continuity. I even placed one probe on the chassis of the unit and the other probe on the power pin and again it shows that there is constant continuity.
When I remove the fuse from the unit, then there is no continuity between the power pin and ground pin. I then placed a probe where the fuse goes and one side shows continuity with ground and the chassis. The other side of the fuse holder shows continuity with the power pin.
Is this normal? Any advice would be greatly appreciated.
