Volkswagon Marine 350 TDI Central Electrics issue

[Boatee]

Hi there,

I have a 2011 VW 350 V8 TDI Mercury Marine branded 4.2 diesel engine. An intermittant issue occurs with fuse S190 blowing on the central electrics board which seems to be the boards postive permanent power feed.

Any suggestions, or even better, a circuit diagram welcome !

Hi there , thanks for the suggestion but no, I had already looked at this Mercury site.
Nb, installation is more about physical items and dimensions , there is no detailed circuit information.
Regards

Thanks Mats but I already have the service manual. This doesn’t unfortunately include low level electrical diagrams.
Actually the diesel I have is branded VW Marine and has a 05B 907 555 central electrics module which appears to have been used later in Mercury’s rebranded electrics.
The diagrams are called ‘current flow diagrams’ by VW and they produce these for every engine of theirs in the same structured DIN format.
