Here's a picture of a transfer switch.
You can safely investigate inside with shore power disconnected. Make sure people around you know that your cord has been disconnected deliberately so they don't help you by plugging it in.
Remove the top cover. There's a wiring diagram inside the top cover. But you'll see 2 thick wires on one end, and a single wire on the other end - just like the picture. The shore power connection is lined up with the output to the circuit breaker panel.
That leaves the generator connection by itself. You'll want to use an allen wrench to ensure connections are tight. Also check the wire connections opposite where the generator is connected.
Check for discoloration or any indication of heat damage.
The other end of the generator wire goes to a junction box situated near the generator. You should also inspect the connections there.
If voltage drops below about 106V AC on L1, the contactors in the transfer switch will drop. If power from the generator (normally 120V AC) is sitting right around 106V, the contactors will chatter.
Again, you'll want to have shore power disconnected. If you're not sure what you're doing, working inside a high-current electrical device could be very dangerous.
