Chassis & House batteries dead
This morning the chassis battery was dead on my 2021 Tellaro 20kt. There wasn't enough juice in the house battery due to several days of rain/overcast skies not allowing solar panels to charge them. I plugged the RV to shore power & after a few minutes, was able to start the RV off the house batteries. A yellow check engine light is now on.
So my question is: would the house batteries drawdown drain the chassis battery?
Does a drained chassis battery automatically cause a check engine light to illuminate?
