Steve, if my brain is actually working, the intent of that stock relay, beneath the seat, is to provide juice from your starter battery, to the dometic fridge. In short, the fridge will only run if the engine is running. When it is off, you run on propane. The relay accomplishes this by receiving voltage from blue wire, at terminal 85, which will close the switch and make terminals 30(from starter battery) and 87(to fridge) common. What GoWesty does is run terminal 87 to their isolator. This makes both sides of the isolator common when the vehicle is running, so both batteries charge. When the engine is off, juice to 85 is off, so it is thereby interrupted to terminal 87, which results in the isolation of one battery from another. The relay could accomplish this by itself (though I think it would eventually melt,) but this enables you to use fatter wire. The fuse panel changes you speak of is actually removing stereo, cig lighter and interior lighting from the starter battery circuit and putting it on the auxilliary battery circuit. The end result being that you only use your starter to start your engine. Brilliant! Miguel
