Some basics which may help to understand any future problems that the books nor dealers explain at all!
We have three systems of electric power which are sometimes separate but also connected at times, so learning which is working and not can be a big help on figuring things.
I first think of the chassis battery system that has the stuff normally found on cars and trucks like outside lights, horn, etc.
Second is the 12VDC sytem which powers inside (mostly?) coach items like vents fans, lights, monitor panels, gas solenoids, furnace/AC controls, etc.
Then there is the 110VAC system which we get from plugging in or generator. Microwave, TV, most all of the outlets will be on this but to make this one confusing, we often find we have an inverter of various output size which may still use 12V battery power to make 110 AC to feed the TV and some of the outlets even when we are not plugged in!!
Small things can give a real headache at times as each of these systems are interconnected for different reasons at different times.
Small points like the way the coach battery is connected to the start battery when the engine is running lets us recharge both batteries a small amount as we drive but it can also make us think our coach battery is okay when it is totally dead!!
The interior lights may work fine when we have the engine running but go out if we shut off the engine???? Totally boggles us unless we know they can get power from the engine alternator and start battery but if the coach battery is dead, they die when we shut off the engine!
So when it seems you have a problem with lots of things, sorting which may work and which not can be a good place to start on figuring which system is REALLY giving the problems.
The inverter may trip if the coach batteries get too low, so perhaps a point to verify before going for repair?
Best advise is to use the RV every week so that you get over the learning curve quicker!!!
