Is the battery the only thing that has changed?

Is the battery charged?
Is it the same when the engine is running (assuming you have some kind of B2B charger)
Do you have a mains charger? Is it the same when this is connected?

Have you disturbed the ground wiring? - It sounds like a grounding problem.
Do you connect Leisure battery and Fridge to Chassis , or directly to each other ( via a Busbar)? Has something changed here?

Loose connection.

Bad crimp?

Too thin cable?

Either way
..... Post a few pics of the connections and where have a look
