2003 Sunseeker House Batteries dies

Be aware that not all motorhomes, especially the older ones, charge the house batteries when the engine is running. If your motorhome is equipped with a Bi-Directional Isolator Relay Delay (B.I.R.D.) device or a Trik L Start, it will charge the engine and house batteries from the alternator, generator, or shore power. Make sure the red switch is in the on position, otherwise, you will not be able to crank the generator, nor charge the house batteries from the alternator or shore power. I would suggest that you first locate the converter/charger, to make sure it is getting power and that power is being directed to the fuse panel. With a multi meter, measure voltage at the house batteries with the generator running, then engine, and then shore power. If the converter/charger is working properly, you should see a change of voltage, indicating a charge. Good luck.
