Confused ????

[V8XR2]

I've fitted an earth cut off between battery and body panel
When I switch off my Noz contoller comes on it has its own earth direct to battery
I've removed live feed to Noz controller
I'm confused

Simple answer is remove the separate earth and place that on the cut out switch so that there are no earth connections on the battery when disconnected. (Which is surely the point of a earth cut off) With any earth path to the battery there will always be the risk of back feeds.
