Dead cluster 2005 clk320 convertible

[Jaffa1965]

Since my instrument cluster came up low voltage,I replaced battery but the instrument cluster now, no longer powers up, and the indicators no longer work along with soft top or folding mirrors.
Any help or advice appreciated

Did your battery throw some big sparks when you connected it?

 

[Jaffa1965]

It did several times

Fuse checking time now then, sparks are a good indication of power spikes which Mercedes really don’t like

Pulled fuses all good.

Then look at the SAMs

sparks are a big no no

Got it booked in for a diagnostic, as I don't have the equipment to investigate electrical equipment

After being taken for diagnostic, found the cat isn't communicating with diagnostic equipment,
