Laura,
The 2 entry puck lights are probably wired to the headlight switch. Turn the switch CCW and they will come on, if your coach is wired like mine.
The battery problem sounds like the echo charger. There are 3 versions and I'm not sure which your coach has; Echo, Magnum, or Bird. All have roughly same function, charge the chassis batteries once the house batteries are at full charge. I think all have some sort of indicator lights that will give you an indication as to what they are doing. The house batteries have to be charged; about 13.2V, before the echo charger will apply a charge voltage to the chassis batteries.
The solar panel will output voltages as high as 15+v but the current available is fairly low so i don't think it's capable of "charging"batteries that are discharged. Its function is more to maintain the battery charge.
Running the geni with the inverter in charge mode should get your house batteries to about 13,2v and then the echo charger should apply a charge voltage to the chassis units. Also, check for loose connections / fuses in the echo charger circuit.
