Earthing the shielded cable

Hi,

I have the shielded cable for the EDIS to VR and EDIS to MJ.

The diagram shows the shield of the VR sensor connected to pin 7 of the EDIS, while the shield of the cable to the MJ is connected to pin 7 and earth.

The effectively means that both cables shields are connected to pin 7 and earth. I have just made up my loom and only connected both shields to pin 7, as that was my initial understanding of the reason for that pin, to provide a shield earth.

Is there any reason to also earth pin 7? This effectively jumpers pins 7 and 9. If this was required why wouldn't it be done inside the EDIS?

Thanks
-Chris

Hi Chris,

I checked my EDIS4 unit with an ohmmeter and found pins 9, 7 and 4 are all connected together internally, so I don't believe you need to additionally earth pin 7 (or 4). I have done as you have and used pin 7/4 for the shields, and works just fine.

Thanks Rich,

For neatness, if I was doing it again I would use pin 4 for one shield, and for the other.

Cheers

Is this a valid set-up ?

Lets hope so, because it's too late now.
