The first picture is your BIM..... Battery Isolation Manager. It is designed to do the following:
- When driving it allows the alternator to charge the house batteries when they drop below 12.6V.
- When on shore power or generator power, it allows the Converter / Charger to charge the chassis battery when it drops below 12.6V.
- It ties the house batteries to the chassis batteries when the Emergency Start Switch is depressed to the house batteries can boost the chassis batteries if it is run down when you try to start the coach.
It is worth checking the wiring..... 90% of the time, Thor wires it backwards where the chassis battery cable and the house battery cables are reversed and on the wrong posts. I have posted about this several time as well. When this occurs, there can be charging as issues and well as issues with the 12V systems such as opening / closing the slide.
