2019 Thor Miramar 35.2 Disconnect status
The BIM is not any type of disconnect switch..... it is an isolator switch that serves two purpsoes.
One - It prevent the house batteries or chassis battery from being overcharged depending on whether the converter or alternator is doing the charging.
Two - it allows the house batteries or chassis battery to be charged when needed from tue converter or alternator.
Some coaches come with a separate disconnect switch and some don’t. My Magnitude has a BIM160 but no disconnect switch so I added one. Now the 2021 Magnitude has a battery disconnect switch added as well.
