Ever since I've had my 1998 450DA both main banks of batteries discharge at the same rate. Am I not correct in thinking that one of the functions of the isolator is to prevent that: e.g. if the refrig is running on 12v and runs down the house bank(stb) the port bank should have full voltage where you can start the port engine and then use the emergency start switch to start the stb engine? I had a new isolator put on when I replaced the charger in 2002, but no change. I took the battery cable off one side of the emergency start solinoid to see if any voltage was bleeding through and it only showed .13v. Has anyone had a similar problem? Appreciate any help. Thanks.
