My MRC AD325 decoder has suddenly died on me and I cannot communicate with it. Can anybody recommend someone to look at it please?

Unfortunately if it is similar to the 324, or 322, you probably have a blown regulator. These are really poor decoders, I bought about 10 of them just to experiment and eventually they all blow up.
I've had the regulator blow, the relay driver blow, and smoke from several.
I would recommend buying another, different decoder.
Does it look similar:?

Hah!
So you got this decoder in 2017, and it lasted 6 years... longer than most MRC....

Hello I have just become the owner of an MRC AD325 decoder. Has anyone got the wiring/connection diagram for it please? Bill

Resurrected!
Been on the workshop bench, for testing for around nearly 4 hours, shows no signs as yet of misbehaving.
Will have wait until Monday for further testing, family gatherings this week end, off to see Great Niece Wilma, nineteen odd years for the second female to appear on the scene.
Then off to visit George III, who's arrival elevated 'Herself' and I, to the auspicious heights of Great Great GrandParents!
Couple of pictures to be going on with............

They usually destroy themselves in acutal operation, often after a short, power interruption, or reversal. They will lock up and only run in one direction or just sit and smoke. The relay will chatter, or the 7800 series regulator will fry.
I bought 10 or so years ago for really cheap, and have blown up about 4 of them. I still have about 5 or 6 that I use with the knowledge they will fail. You can ignore my experience at your peril.
They also do not meet NMRA standards for max track voltage.

Concluded the testing regime, created a decoder template with the Massoth Service Tool program, to produce a the list of known CV's and their values.
Obligatory dodgy video of the decoder operating and controlled via the Massoth DCC System, nothing of note to report.

Things have moved on a little and many thanks to John at the Shed for his help. It turns out that it is not the decoder that is the problem but it appears to be the Massoth system. The Navigator will function as a loco control and a points control but the programming function will not work either on the programming track or on the main. I have operated wireless control ever since I have had the unit – a Dimax 1200Z- for the past ten years and it has worked perfectly. I did try hard wiring it to the Navigator but that did not improve things. Any ideas would be welcome
