Sense wire on the engine battery terminal of the isolator -- is the engine battery as Emery said. Someone above asked how to prevent the problem. Don't run a 100A alternator into an 80A old isolator. I would want at least a 150A. They are not expensive. I run the Yandina combiner across the 2 battery systems at the isolator. Works great an don't have to think sbout it.
I see one other "problem" with ditching the isolator. A bad alternator cannot draw down batteries if the isolator is in place as current can't flow that way.
