ISIS update

[Wodnas]

Sambo, I believe that Isis prefer that the switch earths are run separate to the chassis earth. This is for their system only - something to do with better communication as these signals are only milliamps. They also say that if this cant be done then it will work with a common earth as well. I have run mine separate (Isis system).

Bob,

I have run the switched earths to a common point. The front and rear modules each have a common earth. Previous experience with automotive multiplex systems showed me that most of the errors were caused by poor earths. If you have set common earth points then diagnosis is easier.
