12v Fridge Relay Location

[SnJ]

So our Thetford N3150 will not kick in to 12v when engine is running. Fridge shows spanner 6 and I suspect the relay is defective.

Brief history.
MH failed to start on Friday morning. On attempting to crank the engine the oil level beeped and the engine failed to start. Had to jump start it off our boost pack.
Today noticed that the fridge failed to switch over to 12v.
Looking at the Thetford Diagnostic PDF makes me think that the relay shorted out, continued to draw 12v even though the fridge was hooked up to 230v and flattened the MH battery overnight.

Hence the question
I have a 2009 Autotrail Dakota...
Anyone know where the relay is located please?

Cheers

Could the vehicle battery be so goosed even with the engine running the fridge isn't seeing 12 volts?

Can you start the engine without jump starting?

Yes. Absolutely no issues starting since we jumped it. Stated first time every time.
On a meter it's reading 12.9v. Through the 325 unit it'll boost to 13.5 when charging.

Do I take it the 325 refers to a Sargent 325 ?
If so, there are two possibles.. In the space behind the fridge
In the 325 unit .. There is also a fuse for the fridge on the 325 panel

Yes it's the Sargent 325 unit.
I'll have a look...
