Relay bad? Disconnected wiring? It did work at one time but checked this weekend and it is not disconnecting. TIA

When you say "lights" I assume you mean the interior illumination lights in the overhead?
Those lights will stay on (if switched on) whenever one of three things is powering the DC Buss:
The converter when attached to shore power or the generator is running.
The HOUSE batteries when the USE/STORE relay is in the USE position.
The CHASSIS battery if the cross-connect relay is in the cross-connect position.
So besides a failure in the USE/STORE relay/circuit what you are seeing may also be causes by a failure in the BIRD/BIM/Cross-connect circuit/relay.
I would start by unplugging from SP and lifting the battery leads first from the house batteries, then from the chassis battery to determine where the 12 VDC is coming from.
