What OP has is not an Isolator.
It is a combiner and they are great right up until they go bad. They can be hard to trouble shoot without the main engine running. It can be done.

They called me for the third or forth. I kept them in stock.
I replaced many before my boat repair business was murdered.
Isolators take more engineering to install and make work few builders want to go to that effort of doing. Some chassis makes don't allow it because of warranty. The isolator in my coach is a designed in double diode. It is 44 years and 170Kmile old like the rest of the coach.
