For most accessories, we switch the Hot side of the circuit but with the dual VM we switch the Ground side and why the True Isolator comes with a relay, to control that ground. If you don't want to screw with the relay, you can put s simple toggle switch on the VM's ground lead to 'off' the VM.
my isolator didn’t not come with a relay. I didn’t order the kit just the tru isolator. How does this sound. I have stinger relay and fuse block on hand to install. I am waiting for the aux battery terminal adapters. Should be here this week. I Also have the key on power harness Hooked up to my winch. I am going to move the key on power from winch to the stinger. Run all accessories off the fuse block. Can I leave the volt meter positives hooked to tru isolator and run the ground to the stinger. Then volt meter turns on when the stinger is activated by the key on ignition.
