Solar confusion

Hi, I've got 1 100 watt panel on my bus. And I have a high end capacity deep cycle battery. My battery was housed inside the bus only hooked to my charge controller. I have since then moved my battery down into the side compartment and hooked it up to the main charging lines that come from the alternator of my bus.... Since I've done this my battery drains every night. If it doesn't have a Direct sun charge it will give me an e1 code on the controller.... It's a brand new alternator but the drain is pulling both batteries dead... Before I had integrated both batteries into the system both batteries were fine through the night, now there's a drain on the whole system.... All my wires are correct so I'm really unsure what I'm supposed to do at this point... Any tips would be greatly appreciated.
